new casement window cranks

Question

2 casement window cranks have become stripped (or something) and are no longer functional. I need help in assessing which part(s) to buy.

#'s on the inside of the present handle are 45012 / US patent #4.083.804 / Canadian Patent 1979.

I would need new handles and the crank operator mechanisms - can you tell me what to buy?

I've attached pictures that I hope will help. thanks...Ruth

Hey, Ruth. I would start by looking at our 39-013 and 39-014 casement window operators. These looks pretty similar to your own parts, but you should make sure the dimensions match up before you make a decision. For the handle, see our 39-114L.
