Plygem 1500 traditional window 36x72

Thanks for reaching out to us. I'm afraid I don't know what this is. It looks like it could be glazing bead, which is what holds the glass in the frame. But you describe it as being decorative, so I suppose I'm not sure what it is. Can you kindly verify?

We don't sell decorative trim of any kind, but we do sell a ton of glazing bead. If that is what you have, we need you to remove a small and undamaged sample and show me a clear shot of the end profile. The video below will clarify what I mean.
