I recognize this old operator. Unfortunately,these are not made anymore, and we cannot be sure if anything we carry can work in substitution. The closest we have are our 39-216 or 39-028E. I've also made a list of related parts you may want to look over.

The problem with using either of these two operators is that they will likely not fit your existing sill or sill trim. You may want a local professional to come out and look your windows over to see what they exist. If either the 39-216 or 39-028E can work, they'll require adaptation of your sill and I cannot be sure as to the extent.
