Thanks for reaching out to us. You're correct, that's indeed the glazing. We may be able to help but we would need you to remove an undamaged sample and show us a clear photo of the end profile. Feel free to browse our selection here in the meantime.
Great! Thank you for the additional photos. It doesn't look like we have an exact match for this glazing bead but take a look at our 55-191, 55-194, and 55-206. These are sold in 3' and 6' lengths so it would depend on how much you need. Review the specifications and see if you think one could be adapted to your window.
