Benjamin Vulliamy is regarded as the most widely talented and artistic of the clockmaking family. Born in 1747 he was granted the Royal Appointment as the King's Clockmaker in 1773 and joined his father Justin Vulliamy in circa 1780, carrying on the business when his father died on the 1st December 1797.
This rare and important clock was made about ten years earlier than the month going regulator numbered 330 which was ordered by the Prince of Wales in 1800 for Carlton House at a cost of 70 guineas (£73 - 10s), a standard Vulliamy longcase clock cost 15 guineas.
Number 330 is still in the Royal Collection at Buckingham Palace, unfortunately the original pendulum of No 330 was replaced by B.L.Vulliamy in 1815 with a mercury pendulum but a similar gridiron pendulum to the one on number 220 survives on a regulator made for King George III for use at his Kew observatory and now at the Science Museum London.
