Replacement Casement Operators Needed

A handy person from Chicago says:
Hi,

Hoping you can help - here is a picture. These are probably from 1973 or so. I will be replacing 12 operators throughout the house, and I can change them out to anything equivalent. The window width is 16 inches.

I haven't removed any yet. If you need more info, please let me know and tell me how/where to locate markings that will help.

Thanks in advance!

Greg

Hello, Greg! This looks like the old Pella casement window operator. See our 39-175. I think this is just the part you needed. We also sell the 39-176 for the opposite side.
