Crestline double hung rubber seal on bottom 1996

We sell a ton of different types of weatherseal, but it's not possible to ID what you have without seeing a sample of the original. Since yours is so rotted, then there is a chance we can't help at all.

Is it at all possible to get an undamaged sample? Seeing the end profile in whole condition is the only way that we might be able to find a replacement. The video below will clarify what I mean.
