I see no markings. The arms are approx 12 inches long and the crank is approx 5 inches wide.

Question

I am looking to replace this window crank that was installed in 1991.

Hello! This operator looks very similar to our 39-348 at first glance. Look it over and let me know if you agree, or if you had any questions. We also sell the 36-078 guide, if you needed it, though the original can be reused assuming that this is a match.
