OK, here are some pictures. Unfortunately, I didn't take a pic before I started dismanteling it. Here's its current state (and the state of my basement workbench):



The steel cottered crank, 44 teeth, and pedals and cotter pins:



The bottom bracket and spindle. You can see the notches for the cotter pins. Sorry for the mat on the floor - it makes the picture harder to decipher. I'll try to redo this one.



The chaincase. Normally the chainstay passes through the wide center opening. That tiny slit at the rear gets it on and off the chainstay. Chaincase attaches to the frame in 2 places. The round panel over the chainring pops off. The oblong opening in the round panel probably had a sliding cover at one time.



The front brake and fork. The center wire is from the generator hub. Note that the brake has no fixing bolt, just a lugged cable end that fits in the curled end of the caliper. Fork crown is a horizontal piece of pipe.



The rear brake after removal of caliper and cable from the bike. The two cable ends are part of one cable, and so is the barrel adjuster.



Last picture is the Brooks saddle. I think it says 72L but it's very hard to read.



That's all for now. I'll probably get some more photos eventually.
