I need to mechanisms like the picture. Seems 15" long arm, which is not usual. It is an old conf built on 80's. I can't find the brand for the windows or cranks.

Hey there!
Start by taking a look at our 39-013 and 39-014 operators and carefully review our dimensions to see if this matches your original assembly.
