Replacement For Broken Window Crank

A home owner from Santa Monica, CA says:
Hi Swisco - I am hoping you can help me find a replacement crank for a crank-out window from the 60's. (A burglar broke it while trying to get into my mother's home.) It's "box" is 1.5" deep by 3.125" wide, not including the outside ears where the screw holes were. They were broken off by the burglar. Measuring between what is left of those screw holes I get a distance of 3.875". I haven't measured the arm length yet but I intend to measure it over the weekend. I see neither stamps nor markings. Thanks for your help.

Based on your pictures, I would recommend that you look at our 39-001 and 39-002 . Compare their dimensions to your own hardware and let me know if they can work as replacements.
