Window crank assembly

A quick learner from Alaska says:

I am looking for a replacement for this Roto Casement Operatore. The arm on mine is longer than your 39-092 and shorter than your 39-283.

Any help will be appreciated.

Thank you, Tom

Thanks for posting, Tom. Could you confirm the exact length of the arm? Based on what I see it looks like it could be 6", but I just want to be sure. Let me know!
