Jeremy Evans lists only five un-numbered 8-day spring driven timepieces by Thomas Tompion. All are in ebony Phase One cases and all have the bell set into a cut-out aperture in the large backplate. Two emanate from two of the great 20th century collections, the first from The Wetherfield Collection, inventory number 23, which with the added complication of an alarm train sold at Christies, London, June 2011 for £289,000. The second from the Iden collection, (illustrated in Percy Dawson's overview published by the Antique Collectors Club 1987 on page 87) which is now in private hands.
The cut out was necessary because at this time Tompion used a backplate that was larger than the frontplate. It is a rare feature, but others are known, the latest known to us dates to circa 1687. R.W. Symonds in his standard work illustrates three backplates with cut-outs for the bell:
Figure 174 - the backplate of clock number 22, the angle of the shoulders are comparable with the current lot, however the repeat slots run all the way to the edge of the plate, the signature sits within a full pattern of flowers and foliage.
Figure 176 - the backplate of clock number 66 has smaller, shallower shoulders and the repeat is activated via a Z-bar. The engraving is lighter than figure 174 and more comparable to the current lot.
Figure 181 clock number 96.
A similar engraved backplate with cut-out but a Z-bar repeat system was sold in these rooms and is illustrated in Dzik, 'Engraving on English Table Clocks: Art on a Canvas of Brass 1660-1800', 2019, Wild Boar Publications, p.109, Fig.7.10.
