Crank mechanism

Question

These cranks are for awning type windows installed in an enclosed sun porch of a condo. Bronze colored. For screw holes, I tried to measure from the center of the opening. From all of your pictures I can't seem to find one that matches all three measurements that I took. Are you able to match this?

I believe your operator is an older Silver line part, which isn't made anymore. Take a look at the 39-025 instead. This is a little newer style with a threaded sector at the end of the link arm. I think this can be used as a replacement.
