Old crank out storm windows

Thank you for your patience during this busy season. You have a very old window. The best options we have in our inventory are the 39-001 and 39-002. Look these two parts over and see if you could get either to work.

There's nothing we can do about those springs, unfortunately. They haven't made windows that use springs like this in a long, long time. I'm not sure who may still have them.
