Loking for Rubber Surrond seal.

Question

I believe these are Marvin windows. I am looking for the rubber seal that goes all along the outer edge of the moving pane. See first pic with red arrow. It should be in that slot but it's completely gone. Only number I can find on them is a number on the case lock (pictured) # 31787

I believe the windows to be about 10-15 years old??

Thanks
