I have not been able to find any replacement parts for my windows.
The only markings Ive found are in the crank handle. OPO6-1520.
It looks like Im missing a clip mechanism on the left tip of the crank operator and also Im in need of the 3inch wide part with 2 holes that attaches to the opening window.
The 4th photo is the underneath of a working window.
Help me if you can.
