Parkinson & Frodsham was established in 1801 by William James Frodsham (1778-1850) and William Parkinson (d.1842). Their business continued throughout the 19th century at Change Alley, supplying chronometers to the Admiralty and to shipping lines. Very little of their records survive, although there are some late 19th century records from the firm at the Guildhall Library, London.
In Phillip Arnott's article Chronometers on East India Company Ships 1800-33, the Company is recorded as having Parkinson & Frodsham No. 771, which was in use by Captain Graham on Caledonia in 1822, see Antiquarian Horological Journal, Vol. 30, No. 4, December 2007, p. 481-500.

Condition report

The case is in good original condition. The wood is dry.
There is some bleaching to the top lid.
The dial silvering is worn and a little streaky. The movement runs with would and would benefit from a clean.
The key is numbered, but I think is not the original.
