window openers

Question

I have old windows (1978) with right crank-style operators. 2 styles as follows:
1. 2 holes on top 5/16 inch apart and 2 holes on bottom 1 5/16 inches apart. Opener is 5 1/8 inches long. Arm length is 2 1/2" with a threaded hole which is 1/4 in diameter.

2. 1 hole on top. 2 holes on bottom. 5 1/8 inches long from top hole to center of the lowest bottom hole. One bottom hole is high and 1 is low. Arm length is 2 1/2 inches with a 3/8 inch non-threaded hole. It looks like VE Anderson 39-259 except the arm on my part is not offset.

Take a look at our 39-017 and the 39-094. I believe these are the operators you are looking for. The only difference I found between these operators and yours is the link arm length. However, there is some travel in the gear linkage in the operators which should make up the difference. What do you think?
