I recently got so disgusted with trying to remove that Stronlight crank ( finding a puller ) I sold the PX10 frame and crank attached on the BAY, because I just couldn't be bothered anymore, ( very short attention span ) for about $100. The french have always been sort of odd sizes, threads, seat posts stems etc etc. That said I still love those old classic Peugeots and their kin. When I was a kid and worked in Franks Bike Shop NYC Still there 40 plus yrs later. 553 Grand st NYC, the Peugeots use to come boxed but inside heat shrink plastic wrapped. And I mean wrapped. For every 10 I built, I would guess removing them from their entombment, I slashed the tires of at least 1/4 of them with the box cutter unwrapping them. I guess it was the revenge of the free giving of the Statue of Liberty. Anyway, The real problem with these old bikes, and motorcycles, and cars, is the expense finding the original parts for a reasonable fee. As long as they weren't hit, or chained to a radiator in a storage facility for years with extreme heat, and bicycling is your only hobby, not to bad on expenses, but if you split up your time ( money ) between boating, motorcycling, cars, pets, antiques, family, and other hobbys, it adds up real quick, and not a question of how much you can make off it, but how much you can afford to lose. Reality really kicks in when, doing so with your eyes squinting and you're trying not to look, although you are the only one there, you add up all the real small expenses you put into building this old bike. We all could have probably bought our own Grail bike off EBAY, and not have to have done a single refurbishment. ( and that is said with love and personal trial/error, and unfortunately personal experience ) ) To everyone who contributed here, thank you
