I couldn't help myself when I saw this for sale.
Since I really like miniatures of any kind, when I saw this one, I knew I had to try to get it.
It is of three piece construction, has a quality pin and catch and from the patina on the frame, I would guess silver frames. Unfortunately, the frame is starting to separate from the stress due to the pressure from the pin and hinge.
Can anyone tell the maker?
Here it is compared to a full size.
And here with another enameled miniature.
