I have these windows throughout our 1957 MCM home and only about 3 windows open and more importantly, CLOSE when cranked. I am looking for replacement gears, boxes or whatever else I may need to make them ALL work like new again.

Hello! Your operator is very old, but the design isn't all that different compared to our 39-379. This may be the part you want but please look it over and let me know what you think.
