The presence of the inscription on the dial bezel leads one to consider whether this was perhaps a prototype wall regulator for Denison's three leg gravity escapement. One of his very earliest drawings on the gravity escapement is dated December 1846 but his original drawing of the escapement for the Great Clock, (Vaudrey Mercer, Edward John Dent, 1977, pl. 72) is actually dated on the drawing 27 November 1852 which has to be very close to the date of manufacture of the present clock
