Hello,
After checking our records, we do not carry an exact match for your operator assembly but you could consider the 39-257B. However, I don't believe it will work without retrofitting the link arms. Unfortunately, your original operator is no longer available. We can't make any guarantees that it would work but this would be our recommendation short of replacing the entire window. I'm sorry that we won't be able to offer a better match but please let us know if you have any other hardware questions. Thanks for posting.
As we mentioned, your operator is no longer available. I checked a catalog from 1972 and even then it was discontinued. The best available match would be the 39-257B. However, I don't believe it will be an easy fix. My one issue would be with the 33-067 shoulder screw and if it will fit the window linkage. Though we can't be sure that it would work for you, this would be our best recommendation short of replacing the entire window.
