I do not know kind of crank it is, but here are the markings on it. On the crank arms, outside - SOLIDA, inside - D6 21 Made in France, on the chainring - Made in France, the BB caps - a capital S, Made in France. So I am going to assume it is Simplex. There looks to be provision for an inside, smaller chainring, but finding one could be a trick. I do not have a problem changing the whole bottom bracket, if I need to.
This is the first time I am going to attempt a complete rebuild, so I appreciate any advice given. I have decided to stay with a 5 speed freewheel, that should make our choices a bit easier.
