It was an unusual over-the-counter consignment for Skinner (the vendor's mother had bought it in Europe in the 1940s), and was in excellent condition.
The mounts were thought to be of the period.
Offered in Skinner's quarterly British and Continental furniture and works of art auction on January 7-8, it drew both both trade and private bidders (all of them on the telephone), before it sold at $80,000 (£53,000) plus 18.5% buyer's premium.
The buyer was thought to be a private collector.

The latter had worked at the Du Paquier factory in Vienna and would later oversee porcelain production at St Petersburg.
