looking for these seals on all 4 edges of kitchen crank window

I'm confident that we can supply a match for this weatherstripping, but we'll need a better photo of the end profile. Would it be possible for you to remove an undamaged sample and show us the end profile? It's important that we can see its shape without any bits missing. I know that it's brittle and falling apart, so it won't be easy, but there is no other way for us to find a match. Let me know!
