Thank you for posting! Based on the arms, I'd say that your operator looks similar to our 39-031 & 39-032 EntryGard Dual Arm Operators, but I can't say for sure without seeing what the base looks like. Do these look to be applicable replacements? Let me know.
A home owner from Colorado Springs, Colorado says:
I also have several Oldach Casement Window Cranks arms, which have been broken or malfunctioned. I need your expert advice. Can I replace them with something similar?

Attached are three samples of these damaged cranks.

It's hard for me to identify what you have without seeing either the gearing or the arms. However, since you have similar Oldach windows to the original customer who made this thread, you should start by looking at our 39-031 and 39-032. Compare them to your hardware and see how well they match.
