A Regency mahogany extending patent dining table by William Wilkinson.

Note: The table retains the original patented ratchet mechanism and is stamped on the rails 'Wilkinson Patent Moorfields London.'

When pushed together and folded up, the table converts from a dining table to a side table.

Another dining table of the same model is preserved at Portsmouth in the dining cabin of HMS Victory, Admiral Lord nelson's flagship at the Battle of Trafalgar in 1805.  Interestingly, the table illustrated in Gilbert's A Pictorial Dictionary has a similar naval history, having come from another ship in Nelson's fleet at Trafalgar.

The Wilkinson company specialised in the manufacture of extending tables.  they may well have supplied their tables, including quite possibly this one, to other ships.
