Fentron gears stripped

A handy person from Seatte says:
The interior gear seems to be stripped. Fentron is stamped on the handle. That's all the info I have. Would like to purchase a replacement, possibly more as I work through the house. Windows are circa 1962

It's hard for me to tell what you have based on these pictures. You would need to remove your operator completely from the window for us to get a good look at it. To get started, though, check out our 39-001 and 39-002 , as well as our 39-044 and 39-045 casement operators and see if any of these are a match.
