I have several old casement windows that have the gears stripped on the arms. The operators and the worm gears are all fine, but the arm gears are stripped. By my measurements, your 39-001 and 39-002 would make full replacements possible, but I was wondering if it is possible to just get replacement arms? I have at least 12 arms to replace. Original arms are stamped GETTY Phila, PA.
Attached are pictures.
Thanks for your help
