This is a very old style operator that isn't made anymore. Our 39-332 is similar in design, but I cannot guarantee if it'll work as a substitute. Look it over and see what you think. One important detail to keep in mind is how it attaches to the sash at the end of the arm. Ours uses a little white shoe, but I don't see that on yours. I'm thinking maybe yours just broke off, but I can't be sure.
