I'm back, this time for my parents' house.
Two photos for parts identification to replace the operator assembly. 713WC is imprinted on a trim piece.
Thank you!

Hello and welcome back!

Thank you so much for your patience during our busy season. Take a look at our 39-175 and 39-176 Pella operators and carefully compare our dimensions to yours to see if these match what you need. I'm afraid the covers for these operators are discontinued, but we do carry the 39-109B handle.
