The handle of the brush is marked 925 and OBADIAH.
This comb, mirror, and brush has the three interwined letters we believe belonged to the lady who commissioned the set.
I would be happy to have it looked at by someone who could tell me for sure.
I have only had a couple of Obadiah's items come through my shop.
If you are interested in this set write me for more pictures.
