Having difficulty finding the exact size of this product on your website. In addition to the pic these numbers are on the unit. I am not sure what brand the windows are so not sure these numbers will help. OP051506 or OP05-7533-03 and finally 08:34:40

Hi, thanks for posting with photos!

It looks like SWISCO product codes 39-400, Roto single arm operator, and 39-541, track slider.

You may have the old Roto version of this operator, the difference is the male versus female spline for the handle connection, so you may need to update your handle as well with 39-114L, standard handle or 39-205, folding handle.
