George Hogg, 31 King Square, off Goswell Road, Clerkenwell, working in the heart of London's watchmaking district - the address shown incorrectly in Britten.

Abbott & Garnett, Farnworth, near Prescot, Lancashire, recorded as 'watchmakers' in Trade Directories of the 1834-1851 period, manufacturers of top quality rough movements, often of great individuality.

Dial with faint hair cracks, otherwise complete and the original detent in fine condition. Previously sold as a movement by me and now cleaned and re-cased by its last owner, and working well. NB: the photographs show the movement in its uncleaned state; and detents of this quality now cost in excess of £1500 to make and polish properly, if indeed you can find anyone capable of doing the work.
