It sounds like she was hoping to get a Queen Anne looking glass with the original mirror but it is an Art Deco Barbola mirror. I've looked at the listing. She is talking nonsense: a 1930s mirror, if it has hung in a dry, clean house for ninety years, will still be bright. Barbola is a moulding composition which might contain rubber. Wasn't it a hobby craft material? It is easy to find out what Barbola is.

People like that are exasperating! Make a doll of your buyer and stick pins in it (just joking).
