I'm restoring a house from 1957. It has about 25 windows like this, very few of them still operate, Can they be replaced or restored?

This is a very old Andersen operator that hasn't been made in a long time. I don't think a direct replacement was ever made, but look at the list of hardware I've associated to this page. You may be able to use one of these as a replacement, but there is no guarantee. I'm sorry we cannot offer a more reliable option.

Thanks for the information. Turns out it isn't an Anderson operator, it's made by Standard Thompson Corp. of Dayton, Ohio. In any case that probably doesn't change your answer. I'll try a few of the options that you suggested.
