Crank Operator (1936)
This is an incredibly old window. With that in mind, there's a good chance we won't be able to get you a functional operator, but I will do my best.
To start, can you remove one of the original operators from the window and show me a clear picture of it without obstruction? I'm mostly interested in the design of the arm and the bearing at the end of it. I know your window is painted shut, so this is easier said than done, but we won't be able to come up with a possible substitute without it.
In an effort to be transparent, I also want to reiterate that there is a good chance we can't get you a working match for this part. The effort of removing this part to show us may not be worth it for you, at the end of the day, but it's ultimately up to you. I just don't want to get your hopes up.
As long as the window is unlocked and not obstructed by anything in the frame, you should be able to gently push it open and pull it back in when you're done. It will be more cumbersome but it shouldn't be a problem.
That is a huge help, thank you! I think we can work with this.
My first recommendation would be our 39-001 and 39-002 operators. These are somewhat old fashioned, but they mount to your window in a similar way and they even slide along the same sort of track; ours use the 39-504 but they may even be compatible with your original.
The thing I'm most concerned about is how to mount it to your window. I said that it mounts in a similar way but it's not exactly the same; I would wager that the hole spacing on our part differs greatly from yours, and the size of the larger hole in your sill may not be sufficient. With that in mind, this will likely take some handy work to install in your window, even some trial and error, but I think it's the best option we have available. Look it over and see what you think.
They are not, unfortunately. These are still relatively old fashioned (though obviously much newer than your original parts), and as a result there isn't really a folding equivalent for the handles.
That said, one possible idea is the 39-108 T handle. This has a 3/8" spline, which is good, but it's strictly designed to work on jalousie operators. I'm not sure how well it will work on the 39-001 and 39-002. They're definitely not meant to go together, but it may be worth a shot.
