These are from a SEMCO window in a bronze color. Obviously this one is broken but the insert piece is approximately a 1/4-3/8", with the short side being inset about 3/16" and the long side being about 5/8". These are dark bronze.

Hello,
We'd be happy to look into this for you but we would need to see a clear end profile photo of an undamaged piece of glazing uninstalled to compare to our inventory here. Thank you!
