I thought I'd made a decent score last weekend at the antique store. Picked up a couple of '50s Superspeeds for $5 and $6.95. Took 'em home and tried to clean them up. The Z3 cleaned up pretty well, but had a couple of small spots on the handle where the brass was showing. The B1 had A LOT of brassing on the bottom side of the shave head around where the handle attaches. Looked around for information on how to disassemble these so I could swap the handles, so I could have one of them that looked really good for a daily shaver. Well apparently I got just enough info to be dangerous! I got a set of security bits for a few bucks, removed the retaining screw from the end of the handle on the B1, wrapped a towel around the handle, gripped the handle with some pliers, and proceeded to twist the handle off. No luck, so I thought I'd twist just a little harder. I didn't really whale on it or anything, but heard something pop. I think I discombobulated the linkage for the opening mechanism, and now the silo doors just kind of flop around. The lesson: if you want a pristine looking razor, buy one in pristine condition. Otherwise, be happy with the way it cleans up. Think this will be the last time I try to disassemble a one piece razor. Oh well, only a $5 lesson, so I think I'll live. But I can't bring myself to just throw the broken razor away yet. It just seems wrong!
