Hey Michael. Looks like a bulb seal with a t-base. See the 58-135. Compare the end profile with your old seal and see if you think this could work for you.

Seal 58-135 looks like the one I need for the top of the top window thank you.

Here are some pictures of the seal for the bottom window as it locks to the top window.

This is not one that I'm familiar with. Can you tell me if part of it tore off, or is this all there is?

I do wonder if our 58-055 can be used as an alternative. The design is different but it is very commonly used on casement windows, and it looks like it might function in more or less the same way. However it would depend on if there's more to this sample than what I see in your second photo here.
