Notes
Note: The escapement of this watch is similar to
that patented in 1857 by G. Morton (Eng. patent
No. 2432), and to the Patent Union escapement
patented by G.C. Kelvey and M. Holland in 1863 (
Patent No. 2184). All such movements appear to
derive from the workshop of Henry Fletcher at
Prescot, Lancashire.
