Are bow front cupboards always corner cupboards?

No, but the corner form dominates. Of 316 listings, 201 titles say "corner", and "front corner" alone accounts for 116. The rest spread across bedside cupboards and chests, linen presses, tallboys, wardrobes, and side and cocktail cabinets, all sharing the same curved facade.

What wood are they usually made from?

Mahogany accounts for around half of the titles and oak for roughly a fifth. Walnut takes a smaller share, and 15 of those are burr walnut. Pine, elm and satinwood surface occasionally, as do lacquered and painted surfaces.

How old are most of these cupboards?

"Georgian" appears in 134 titles, far outweighing Victorian at 18 and Edwardian at 16, and "George III" turns up in 27. The dated field runs 1700 to 1960. Only 93 of 316 listings give a clean year, so period labels carry most of the dating. The earliest clean date recorded is a c1710 chinoiserie bow fronted corner cupboard.

Do they come up often?

Around 36 come to market on Sellingantiques in a year, and 103 different dealers have listed one. That spread suggests a category almost everyone in the trade touches occasionally rather than a specialism.

Which are the unusual forms?

Continental pieces are the scarce ones. Dutch, Danish, Swedish, French and Italian examples appear only once or twice each across the archive. Odd single forms have included a bow front music cabinet, a double bow front burr walnut cocktail cabinet, a corner medicine cabinet and a bow fronted corner wardrobe. Miniature and apprentice pieces surface now and then.

Were any made by named cabinetmakers?

Not in this archive. A scan of all 316 listings turned up no maker names, and only one title names a retailer. These are described by timber, period and form rather than by workshop.
