Hello,
Your operator resembles one of the Encore style pairs shown in our video below. The determining factor would be the fitting that attaches the straight arm to the sash track.
If you need new hinges as well, the 36-048 would be a good place to start, depending on whether the 10" long base matches yours. Thanks for posting!
