The colored bits that go over the shell handle covers were originally celluloid. I assume the makers of these lasted long enough to eschew celluloid, but I don't know how old this one is. I may have bought it at West Michigan's original big-box store in the mid 70s, or it may be a flea market acquisition.
Maybe I'll have to bugger with it. Probably with real bolsters and all. I'll color the head "bolster" to get a little better idea of whether I can get away with making it a barehead. It's a cheap old knife, but a good one, and the biggest jack I've got. I think I'll sand off that failed chrome too.
