TJR Trading has dated this piece to the 1890s.

The mirrored plate has a chip to the edge. There appears to have been some restoration to the body, which is particularly noticeable on the side of the frame where the mirror is darker in a demi-lune. Other areas are a slightly different colour to the rest of the body which could indicate repairs or wear.

The mirror is in good, usable condition. Often the backing of the mirror plate has deteriorated, but this hasn't (it may have been replaced). Often they can be a bit wobbly and you can hear pieces moving around inside. That is not the case with this example.
