Продано: Antique enamel. Attribution and evaluation

[NATA NOVA]

I would be grateful if the knowledgeable help with attribution (and evaluation) of this thing.

Several years ago, when she first came to me, I had a feeling that this is part of the toy headset, a small stool in the rococo style. Seat-enamel (vitreous enamel-painted poemali) for copper (in the corner-tiny chipped). legs and the rim of the metal bronze color with a simple engraving (snake with dots). Under a 10-fold increase in the pits, traces of yellow metal. On the back of enamel inserts a piece of extremely fragile cardboard (?) Teemno beige. Cardboard closed velvet the same color.

  In visiting the British transfer "Antic Roadshow" (in America) once viewings of the toy (works!) Mechanical piano with rospisnymi emalnymi inserts, mounted in metal .. that style drawing (painting), color scheme, clothing, metal framing and proportions were identical to my stool. The first feeling was that this harpsichord (piano) and my stool-set.
The specialist explained to the owner that this is "historicism" -T.E. 18 th century forgery under the 17th and recommended insurance for $ 2000 -3000 $ ..

Shl: why the price seemed to me a spoon with enamel on the "Trinity" overpriced ($ 2000) ..

Are there any considerations?
Thanks in advance!
