Windows edge weather stripping and 1 window crank.
Seeing the groove doesn't tell us much. I'm afraid these photos also don't narrow down the list of possibilities. The only way we can match this up to something in our inventory is to see the end profile. The video below may help explain exactly what we need to see.
Please also make sure the sample you show us is as undamaged as possible. I know it will be difficult since yours is so brittle but if any pieces are torn off or deteriorated away then we can't help. Please try your best.
Thank you, that's perfect. Start by looking at our 58-056E. This is very similar to the seal you show in your photos in terms of design, but I have one major concern, which is size. The 58-056E is made to work on doors, not windows, so I worry it may be too big. Refer to the dimensions below to confirm.
