Trying to find the right operator

A quick learner from Casement Operator says:
I have a older casement window, I believe it is a 0971 series Alside casement. I am thinking that your 39-221 operator is the right one for it. I have included a picture of the casement that still works with the operator I am looking for. Thanks for the help in advance.

Thanks for posting! I agree, our 39-221 Maxim Dyad Sill Mount Operator seems to be a very close match. I see that your arm measurement is 4-5/8", while ours is 4-7/8". However, our measurement is from edge to edge, not hole center to hole center, so I think yours might be 4-7/8" as well.
