Thanks for posting, Eric, and for the great picture! Please take a look at our 39-025 window crank operator. Do you think this might work for you?

I have a similar crank needing replacement. The housing has similar dimensions as your 39-025, except the drop arm is only 1 and 7/8" in length.

How about our 39-251 & 39-252? These look like they might be closer. Let me know if you agree.
