Need help in identifying weatherstripping on bottom sash of Marvin window

Question

I have Marvin double hung windows (EZ Tilt) which were installed about 1990. As you can see from the attached photo, the weatherstripping on the bottom of the inner sash is totally shot. I believe there was originally a soft round vinyl bulb that flattened against the jamb when the window was closed, but most of the bulb has disintegrated. Looks like the bulb is about 3/8" when flattened, but I can't tell what the original diameter was. Please help me to identify what I should order for a replacement.

I'm afraid I cannot identify what you have based on this picture. The weatherseal is just too deteriorated. Is there any sample on the window that isn't as damaged? Perhaps if not on this window, than an identical window in the house? Without seeing a clean shot of the profile, we cannot be sure what your window used.
