Glazing Bead

I'm afraid these photos don't tell me what you have. In order to ID a match, we will need to see it from the end profile. That way we can see the shape. The video below will show you exactly what I mean.

It must be stressed that the sample you show us must be undamaged; if any part of the end profile has broken or crumbled off, we won't be able to match it up. Just something to keep in mind.
