casement window crank parts

Contractor from 06277
cant seem to find the identical part. the windows have no markings as to brand name.  crank mechanisim has no visible markings as well. looking to replace with OEM if possible.  I am assuming the windows to be about 20 years old.

Hello,

I believe you have an older-style operator used on Andersen windows between 1960 and 1970. Unforutnately, we do not carry this older operator. You'd need to contact Andersen directly to confirm if an exact match is still available. 

We do offer the 39-365 operator, which is similar, but it has a metal roller at the end of the arm instead of the square nylon bearing shown in your photos. Take a look at the specifications and the two types of tracks related on this page to see if you could adapt these parts to work for your window. Also, see the related videos on the website. Thanks for posting!
