Tom Scott Antiques has dated this piece to the 1880s.
Good decorative frame and ribbons to the top.
Some very minor knocks over its lifetime, but nothing of any concern.
You can see what I mean from some of the detail photos, the very faint diagonal haze.

In all, a very good quality oval gilt mirror that has been allowed to age gracefully and it is of a really good size, so would hang well an an overmantle mirror as well as free hang above a console or chest of drawers perhaps.
Measuring:
44” or 112cm high
34” or 86.5cm wide
3 1/2” or 9cm deep
