Number 2108 inside crank handle

Question

Hello,
Looking to replace 2 broken crank handles for our kitchen window. Only marking is the number 2108 on the inside of the handle. There doesn't seem to be any set screw, just a rivet.
Thank you

Thanks for posting. That code is often associated with the 39-205 Folding Crank handle, which can fit splines that are 11/32" in diameter. Take a look and see if you think this crank handle could work for you.
