The Fancy Fox has dated this piece to the Victorian era.
There is no makers' mark but the same set of Schoonhoven marks have been seen on pieces that are further marked for Hubertus Hooijkaas so this is a possible attribution. The folding cover has a lion passant mark, the interior bears the Dutch lion and key mark (indicating made for export) and there is also a gothic letter L stamped to the front left leg.

It measures 5.7cm (2 1/4") wide, 4.3cm (1 11/16") deep and 5.7cm (2 1/4") high. It weighs 81g / 2.6ozt. Condition is very good overall but there have been 2 repairs to the stretchers and so the front left leg is approx. 2mm shy of the table surface but this isn't noticeable aesthetically. The hinge is fine, surface wear is light and the marks are all clear.
