I have quite a few of Canadian made Proto and Proto-Challenger. I purchaced most of them back when I was an apprentice working in a machine shop. Good thing I got the company price. I also have alot of USA made Proto. I think they quit making them in Canada in the mid eighties. Missing a few of the metric wrenches but complete wrench sets and sockets. Ratchets from ¼" to ¾". Side cutters, end cutters, hammers, adjustable wrenches, torx drivers, breaker bars, speed wrenches and even allen wrenches. I don't have many pictures yet but here are a few.
