On the lock of this replacement window is a s printed with 3 straight lines like an inverted z. On this pivot pin is a pattern number 4926524. It is 2 3/4" long.

I recognize this. I think you might want to look at our 26-197. This appears to be a good match for your pivot bar here, but check it out and see if you agree.
