Antique Perfume dabber bottle on chain

I have not identified the maker of this piece. The makers mark appears to start with an H and end with a T with something in the middle. It also has marking for 9 k for the top and bottom but the sides are marked as plate. This is not that unusual as parts of pieces like this may be solid and other not. 9 k rose gold hallmarked solid 9 375 top and bottom and the sides are 9-375 gold plate.
