Acorn crank window handle

A quick learner from North Carolina says:
I'm looking for a replacement for an Acorn crank window handle. There are patent #s on the back: Canada patent # 45003 and 1979 date and US patent # 403326.4 (I think. The US # is worn and hard to read). Thanks for any help you can provide.

Hello,

We'd be happy to help but we would like to see a photo of the operator that your handle attaches to with the window open so that the arms that move the sash are fully visible. This will help us confirm which handles would be compatible with your assembly. Thank you!

Thanks for getting back to us. Your operator resembles the 39-067 shown below, which is compatible with the 39-114L handle. Take a look and let us know if you have any other questions.
