Roll Out Window Cranking Mechanism Replacements

Question

Looking to find replacement components for window cranks and or mechanisms for a house built in 1954. The only identifier is a patent number: 2732726  on the component labeled Side crank, for discussion. The patent number is viewable on the USPTO website. The windows are approximately 35" wide and roll out horizontally (up and down). The house is being renovated and historic requirements apply.

Thank you for reaching out to us. The operator in your first three photos is no longer made, unfortunately. Our 39-389 and 39-390 are the best options in our inventory but we can't promise they will work for you. As for the other operator, take a look at the 39-005, 39-346, and 39-165K. Review the specifications for these parts and see how they compare with yours.
