Subject: [CR] Chain for 3 spd Cyclo derailleur

Hi CR folks, I'm trying to set up a cyclo based 3 speed drive train on a 1950's French bike. At the time I got the frame, I also got what was purported to be the R. derailleur, shifter and crank/bb from said frame. A standard 5 speed chain will not fit the chainring, which seems 1/8" compatiable. 5 speed chain seems to fit the 3 speed cyclo freewheel fine. Is it most likely that the crank is incorrect, or did old cyclo 3 speed drivetrains in fact us 1/8" chains? Thanks much for the assistance.
