Replacement parts for windows part #Interlock 12C1S23 and part #41357 for cranking the window open

Hello! Your operator here appears to match our 39-239B. We also sell the 39-451 cover, in case you can't reuse your original.

The hinge is unfortunately not made anymore, so it's not something we can replace. However some professionals in the past have told me that they were able to adapt our 36-048 for use in this window. Look it over and see what you think. It's not going to be an easy 1:1 fit but if you're handy I think you ought to be able to make it work.
