Antique Art Nouveau Peacock Feather Silvered & Enamel Belt Buckle c.1900

This is lovely piece of Art Nouveau silverware that is both decorative and wearable if desired. I've bought and sold many belt buckles (or nurses buckles, as they've become generally known in the U.K.), but it's been some time since I've seen one as elaborate and decorative as this example. The design is pure Art Nouveau - the buckle is formed in two halves, with each being wing like in form. To the reverse side is the usual clasp consisting of a 'hook and eye' type mechanism, plus a retaining bar to each half to enable a fabric belt to be threaded through it. Within each half is a stylised representation of a peacock feather, with a vibrant foil backed blue-green enamel cabochon to represent the 'eye' seen on the actual feathers. There is a further rectangular foiled enamel panel at the centre, which is there no doubt to disguise where the two halves meet. Around the edge of the buckle's frame there are more stylised peacock feather motifs with their distinctive eye shapes. The whole piece has been die stamped and has a silvered finished - I make the assumption it's silver plated based on the fact there are absolutely no marks whatsoever. A solid silver piece of this kind of quality and design would undoubtedly carry a silver mark, or at the very least a good quality makers mark. In the last image you can see four score marks in the metal to the reverse of the buckle, plus the same on the other side, but these appear to be the only kind of mark apparent. The whole piece was black with tarnish when I acquired it - I've gently cleaned the front to bring out the lovely enamel colours, but I've left the reverse as found. Given the high Art Nouveau style of the piece, it will date to circa 1900, and may even be very late 19th century. I've owned a few of these silver plated buckles in the past, and curiously they rarely seem to carry any maker marks. It goes without saying that were this a hallmarked solid silver piece, either British or Continental, the price would likely be many hundreds of pounds, judging by examples seen in specialist decorative art galleries.
