Meyer Isaac Tobias, Poole Lane, Liverpool, one of the most respected English retailers of watches in American, until his death, in New York, in 1838. See 'English Watches for the American Market, a History of Watchmaking by the Tobias Families of London and Liverpool' by Michael Edidin, published in the October and December 1992 issues of the NAWCC Bulletin.
Edward Massey, Newcastle, Coventry and Liverpool, 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 least common, 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.
Dial chipped and cracked and lacking hands. Otherwise complete and in very good original condition. Not cleaned by me but will tick happily when wound.
