Pair of 19th century bronze sconce

This pair of very high quality wall lights is identical to an apocryphal model made around 1770, and is similar to a Pitoin model made for the Martyr Queen.
A wide ribbon tied to a nail bears vines in the lower part and lily buttons (?) under the rosette. The two fluted arms are seized by a knot; they are dressed in foliage and carry a vase vase and a large counter cup, all fluted and surrounded by pearls.
These sconces bear the hallmark of the Colin house, which was a great bronzier of the second half of the 19th century. Their narrowness without these lights being small also makes it possible to use them on either side of a mirror, in fact, they are in the model of wall sconces.
We are very close to the work of the 18th century.

Condition:
Excellent condition, beautiful luminous gilding. We were electrified but without the usual drilling, so invisible, and easy to reinstall.

Dimensions:
Platinum height: 57 cm x 10 cm (at the knot, otherwise 8 cm). Wingspan: 26 cm, overhang: 20 cm.
