The case of the present clock was purpose made by Derek Roberts Antiques to utilize a fine and unusual regulator movement. It was copied from another Charles Frodsham wall regulator, No. 1562, illustrated in D. Roberts, English Precision Pendulum Clocks, Atglen, 2003, p. 159, figs 19-24A-E.
Edmund Denison, later Lord Grimthorpe (1816-1905), produced several designs of gravity escapements for the Great Clock at Westminster Palace built by Edward John Dent (1790-1853). The double three-legged was chosen for the Great Clock and also widely used in other turret clock movements. The four-legged variety was favoured for astronomical regulators. The present clock escapement differs from Denison's original design as the legs are formed with an integral steel ring giving them more rigidity. No. 1562 also incorporates this design.
