Window crank assembly

A quick learner from Panama City Fl says:
10-8201 stamped inside of assembly. I assume this is called a right hand crank? I would like to order one right hand crank assy. And one left hand assy. If they work I will order about 15 of each right and left assy.

I believe you have a Trueseal brand operator, which is unfortunately no longer available. You will need to use a newer style type operator. That said, take a look at the 39-056. The supplier suggests using this as a replacement for their old part. Take a look and see if you can adapt it to your window.

Thanks for the information , what I believe to be the left side crank assembly has 10-9201 stamped in it. Could you give me the replacement part number for it also?

Those stamps don't really tell us anything, I'm afraid. Is this the opposite hand side of the operator pictured above? If so, the opposite side of our 39-056 is the 39-055
