Good London finished movement with Massey lever escapement, circa 1820.
18-size Lancashire fullplate fusee movement, jewelled to the 4th, with cap jewels on balance (diamond), lever and escape, the cap stamped LxR, as often seen on the best London work of the period. Massey type-3 detached lever escapement, with short lever and early pallet shape. Gilt balance with poising screws, spiral balance-spring. One-piece cream enamel, gold hand. 46 mm diameter, 14 mm deep, not including centre arbor.
Edward Massey, escapement manufacturer and Patentee of the first extensively used detached lever escapements. Catalogued in recent times by Alan Treherne, the various types have come to be called from 1 to 5. Types I and 5 are the earliest and now very difficult to find in good condition, followed by type-2 and then type-3. Type-4 is a seconds beating-variant, usually fitted with a type-3 roller, and is very rare.
NB: It is my belief that many Massey type-1 steel rollers were replaced with type-2 and particularly type-3 jewelled rollers as soon as they became readily available in the1820's. The fact that the pallets in this movement appear to have no draw would tend to confirm this has happened.
Replaced minute and no seconds hands and a edge chip in dial at 12. Otherwise an unusually well finished Massey lever movement, surviving in the condition it was delivered to the retailer for them to add their name and number, which obviously never happened - priced lower because of this. Not cleaned by me but will tick happily when wound.
