Question

I took pictures for what im looking for. I couldn't find it on the website. The numbers on the frame was the only info I could find.

This looks like older versions of the Roto short-arm operators, the 39-091 and 39-092. Unfortunately, Roto has discontinued a number of parts related to these operators over the years, including the bracket arm that connects the operator's short arm to the window. Apologies for any inconvenience.
