Windows operators

A home owner from Puerto Rico says:
HI, mine name is Efrain and I can not find a window operator to replace mine. My operators have not any stamp or mark on it. I am including the dimensions and some pictures. Please, let me know if you have some of them.

Thank you for posting. Look at our 39-074 and see if this is a good match.

Hi Dave,
The arm of the 39-074 looks straight, please can you confirm? The arm of my window operator is offset to the left as the drawing and picture shows.

Ahh, I see. I'm sorry, I missed that. In that case, see our 39-411. This might be a better match.
