Peach tree casement seal
The only part we carry in regards to the operator in your photos is the handle, our 39-148. As for the operator and related parts, you will need to contact a Peachtree dealer near you to see if they can still supply.
Unfortunately, we don't have an exact match for this seal but check out our 58-053 and 58-055. See if you could adapt one of these to work as a replacement. If you want, you can order samples of each here.
Unfortunately, we can't process an order through this discussion board but you are welcome to do so by using the links I've provided or you can give our customer service department a call at 856-317-6263 for assistance. Thanks for posting!
