1901 Columbia Chainless Cranks

[fat tire trader]

I am looking for a crankset for my 1901 Columbia Chainless

I have an earlier crankset and a later one. Neither seem to fit.

I'm assuming, that there are at least three different generations of cranks for Columbia Chainless bikes.

Does anyone know what years the cranks changed?

Thanks,
Chris

I have a crank arm set and front dust cover for sale on ebay right now.

I have a crankset like the one that you have for sale. I believe it is one or two generations newer than the crank that I need. If you look at the drive side part of my bottom bracket, it has two notches. I think it needs a crank that has two bits that fit into those notches. The other side of my bottom bracket is the opposite, it has the two bits poking out and will fit with that side of the cranks that we have.
