Trying to find correct replacement parts for Caradco casement windows. There are two different style operating mechanisms.
The smaller bay window, has Truth hardware with # 30637 stamped on longest part,about 4 1/2".
One of the other windows has Entry Guard Truth #20755 stamped on it, and has what looks like a 9 1/2 arm.
Is there a way to match parts based on the #'s?
I have also attached a few photos.
Thanks......
