This photograph shows a stand at a trade show in the 1920s or 1930s. The company represented is Rainbow Protex, a manufacturer of auto top dressings and boot and shoe polish. At this period, car roofs were usually made of fabric that had been coated with rubber. To keep them looking good and to protect the rubber from the effects of sunlight and cold or wet weather, black oil-based varnishes known as auto top dressings were applied to their surfaces.
This particular company’s head office was in Toronto, but (according to the photograph) the factory that produced the polishes and dressings was in Deseronto. One of the men in the photograph is William Macdonald Mackintosh, a chemist, originally from Liverpool in England (U.S. patent no. 771,257 was issued in 1904 for his ‘Compound for Waterproofing Fabrics’). Mackintosh’s granddaughter got in touch with the Archives recently, asking whether we had any information about the company for which Mackintosh was working.
We don’t have any details about the firm in the Archives, so, with her permission, we are sharing this copy of Martha Mackintosh’s photograph here, in case anyone can tell as more about this particular company. We would like to know exactly where in Deseronto its factory was and when it was in operation. Please comment if you can help!
