Going My Way? Conservation of a Streetcar Sign

Post by Angela May, Conservation Intern

The Collections and Conservation Department hosted Angela May on her 15 week curriculum-based internship between September and December 2018. This internship was the final requirement for Fleming College’s Graduate Certificate in Cultural Heritage Conservation and Management.

First, the loose dirt and dust was removed from the iron frame using a brush and vacuum. Some packing peanuts that were caught on the interior of the frame were also removed using tweezers. Next, a fibreglass bristle brush was used to gently remove corrosion from the frame. It was a slow process to remove the corrosion from all sides of both the exterior and interior of the frame, the front of the metal straps that held the glass in place, as well as each little screw that fastened the straps to the frame.

Because the back sides of the metal straps holding in the glass were unpainted, I was able to use the air abrasive machine with plastic media to more easily and quickly lift the corrosion from these pieces.

Once all of the corrosion had been loosened, I again brushed and vacuumed the artifact to lift the dust that had formed from the corrosion being removed.  I then “degreased” or lifted the rest of the corrosion still left on the surface with saliva and cotton swabs. The enzymes from the saliva help to lift the corrosion without damaging the painted surface like some solvents would. Science!

This took many, many swabs!

Next I began work on the textile number rolls which were covered in dirt and stains (some of the black paint was also lifting). To lift the dirt, cosmetic and soot sponges were used until they came up clean. Water and Orvus, a near-neutral pH anionic detergent, were tested on the surface to see if the yellow stains could also be lifted, but the paint was soluble in water so no further interventions were pursued.

And there you have it, one clean and rust free (for the most part) streetcar sign. You can see this artifact in the upcoming Strike 1919: Divided City exhibition, which commemorates the 100th anniversary of the Winnipeg General Strike opening in March 2019.

Visitors to the Manitoba Museum are currently enjoying two hockey themed exhibitions – Hockey: The Stories Behind our Passion from the Canadian Museum of History and Manitoba Heart of Hockey developed and produced by the Manitoba Museum. Both exhibitions examine the meaning of hockey in the lives of Canadians as players and their families, coaches, officials, broadcasters, and fans.

One person who literally helps to keep the game running smoothly is the skate sharpener. A trained operator can optimize a player’s performance by skillfully honing the pitch and contour of the blade to match their stride and style. Recently, the Manitoba Museum received a donation of an early skate sharpening machine along with the sign for “Vimy Skate Sharpening” run by Allan Merko.

Allan Merko was a Canadian lad with a passion for hockey. Times were tight growing up in Gilbert Plains, Manitoba, so Allan collected bottles to cash in for the deposit in order to pay for his basic equipment – skates, gloves, and a stick. After a move to Ethelbert, he played centre for the Ethelbert Eagles and later the Sabres wearing jersey No. 9. His skill and speed on the ice earned him the nickname “Squirrel”. Later, he would take up coaching the younger Ethelbert Oilers team and teach power skating. His daughter fondly remembers growing up as a ‘rink rat’ and hanging out with her dad.

Allan was more than just a player and coach. He also operated the Zamboni and created and maintained the ice at the Ethelbert Arena. Sometimes he flooded the ice between periods in full hockey gear while his team rested in the dressing room! Being mechanically inclined, Allan taught himself how to sharpen skates on an unused machine in the arena thus saving local skaters a 125 km round trip to Dauphin.

The Manitoba Museum receives calls daily inquiring if we are interested in receiving artifacts or specimens for our collections. They may have collected some clam shells while on a family outing to the beach, or have found some “treasure” in Great Aunt Muriel’s attic. We never know what to expect until we actually see the item.

In the spring of 1993, we received a call from a woman near Arborg (Manitoba) asking if we would be interested in receiving a butterfly collection. That may sound unusual to some, but for museum staff that work with insects, it’s a common conversation and potentially a good acquisition. What WAS unusual was where the butterflies were currently being stored…… the caller described that they were in a derelict van on the property they had recently purchased! After hearing this, we imagined the worst and didn’t expect to bring much back to the museum. Dried insect collections are highly susceptible to mould and live insect activity. A collection that is exposed to either of these factors can be completely destroyed within days.

Once back at the Museum, the entire collection was placed in our large freezer for pest treatment. This is done to ensure that we aren’t inadvertently bringing in any live insect pests that could damage the Museum’s galleries and collections. When the 2 week freezer treatment period was complete, we started the massive task of inventorying the collection. The collection consisted exclusively of butterfly and moth specimens. There were upwards of 400 expertly pinned specimens with data labels, and approximately another 200 specimens still in their original glassine collection envelopes. As our work progressed further into documenting and cataloguing each individual specimen, we realized that it included some very special and rare specimens.

Among the many specimens of this collection, one species stood out. There were 26 specimens of an extinct butterfly, the Silvery Blue (Glaucopsyche  lygdamus xerces; Family Lycaenidae). They were  collected in the 1920s by R.F. Sternitzky from the dunes of what is now the Sunset District of San Francisco, CA. This butterfly was endemic to the almost uninhabited coastal sand dunes of this area at that time. The species was first documented in that area in 1852, and is believed to have become extinct by the mid 1940s, when the dunes were scraped clear and houses completely replaced the dunes. Its extinction was directly attributed to urban development and habitat loss that included dune plants that the species relied upon for food and egg laying.

The majority of the butterflies and moths were collected by R.F. Sternitzky in the coastal regions of California in the years ranging from the 1920s to the 1940s. There isn’t a lot of personal information on the web about R.F. Sternitzky, other than he was born in California (1891-1980) and spent a life time collecting mostly butterflies and moths (also some bees, flies, and ants) in parts of California, including the San Francisco Bay area, and in his later years, Arizona.  He contributed significantly to Lepidopteran (moth and butterflies) collections and subsequent research as is evidenced by the numerous ecological and taxonomic publications online that refer to his specimens. His specimens are deposited in several large American museum collections including the the Essig Museum of Entomology (University Of California, Berkeley, CA), Bohart Museum of Entomology (University of California, Davis, CA), Yale Peabody Museum of Natural History (New Haven, CT), the Smithsonian National Museum of Natural History (Washington, DC), the Harvard Museum of Natural History (Cambridge, MA), the American Museum of Natural History (New York, NY), as well as in Canadian museums such as the Canadian National Collection (Ottawa), and now the Manitoba Museum (Winnipeg).

This home chemistry set came into the conservation lab for treatment after being selected for display in the soon to be constructed Winnipeg Gallery which is part of the Museum’s Bringing Our Stories Forward Capital Gallery Renewal Project. The set was acquired by the museum in 1979 and was manufactured by Lotts Bricks Ltd., a toy company based in Waterford, England. 

It was noticed during an initial condition report that the cardboard insert was weak, ripped, and warped in several locations and needed to be stabilized before display. Since the cardboard had warped over time, the loose and broken parts would no longer fit together and therefore the cardboard would need to be reshaped before repair could be completed. 

The chemistry set consists of a red cardboard box which has a grey blue box adhered to it. There is also a moss green cardboard insert which holds the pieces of the set in place. There are twelve cardboard canisters with pop-off metal lids, and four glass bottles with metal screw-on lids. All of these containers still have their labelled chemicals inside. There is a small glass tube with a cork stopper which containing purple coloured litmus paper. Hidden under the cardboard insert is a small envelope labelled ‘Litmus Paper’ which has two pink papers inside. Lastly, there is an orange rubber tube with a glass end covered in a black coating. 

In the conservation lab, the set was disassembled and the individual parts were examined. In general all surfaces of the set were dusty and covered in grime. The red outer box was very stable but the moss green cardboard insert was ripped in several areas and the structure was warped. The canisters and glass bottles have small areas of corrosion on the metal lids. 

The first step was to clean every surface of the set. This involved brushing all the components with a soft natural hair brush which loosened dust off the surface and allowed the dust to be carefully vacuumed away. The cardboard and canisters were further cleaned by gently rubbing eraser bits over the surfaces to pick up grime and loosen ingrained dirt. 

The most complicated step of the treatment was reshaping the cardboard insert. The insert was reshaped by misting the surface with distilled water, causing the paper structure to relax, which allowed for the manual repositioning of the cardboard to the original position. The insert was placed onto custom cut wood blocks which were covered in absorbent paper (blotter paper). The wood form was clamped and weighed down which prevented the cardboard from deforming during the drying process. 

After a week, the cardboard insert was dry and removed from the wood form. The cardboard was then repaired by reattaching the loose sections and reinforcing ripped areas with light-weight mending paper and conservation grade cellulose based adhesive. The ripped cardboard was further repaired on the front of the insert by adhering tinted light-weight mending paper to breaks in the structure. 

Once everything was stable and dry the insert was set back into the red box and finally all the components were set back into place. 

You will be able to see this home chemistry set in the new Winnipeg Gallery when it opens in the fall of 2019.

I was lucky enough to work alongside a group of intelligent and hardworking colleagues, whose passion for museum work was evident from day one. The support and direction I received from both Cindy Colford, Manager of Collections and Conservation, and Roland Sawatsky, Curator of History, was invaluable. I also would like to thank Loren Rudisuela, Carolyn Sirett, Nancy Anderson, Cortney Pachet, and Amelia Fay and numerous other staff members for all the help they provided me over the last few months. The Manitoba Museum truly employs a special group of people.
