1950s long straight arm window crank replacement

Question

Hello,

Looking to replace two sets of crank out long straight arm window openers. It does look like the arm is attached in a floating track with a screw. The arm looks to be approximately 8" from where it bends and maybe 1" from outside to inside where the crank house sits inside the window. Can you suggest replacement left and right sets?

Hello, thank you for posting,

Please start by reviewing the style and dimensions of the 39-001 and 39-002 operators to see how they compare to your original. We recommend detaching the arm to view the end that fits into the track to confirm the style is the same. Let us know what you think and if you have any additional questions.
