Casement window insulation from old Wellington Windows - out of business

A home owner from Milwaukee, wi says:
Since they are no longer around, can't find suitable insulation for several casement windows. Closest that I could see on your site is possibly 55-183-3 and 58-200. I hope my pictures are suitable. Thanks, B Baum

I'm afraid that I can't identify what you have based on these photos. You'll have to remove a sample of the original and show us a clear shot of the end profile. That will allow us to match it up to something in our inventory. The video below will show you what I mean.
