Hello, This is a very old Roto brand part that was discontinued. A newer model was in production for many years but that was also discontinued. At this time there is no known working substitute. We do have a theory that our 39-221 and 39-220 operators might work as a substitute. Unfortunately, we don't have these older Roto windows to try them out on. I'm afraid there is no confirmation at this time. While we cannot guarantee that they'll work, we can also guarantee that you won't find anything better. If you want to try them out, you'll also need new 39-205 handles, some 39-508 stud brackets, and some 39-105 detach clips. We'd be very interested to know if these parts work out, but we understand if you didn't want to take the risk. I'm sorry that we can't offer anything else at this time. |
