What does "afaik" mean?The single sheet engraved silvered dial was the last form of brass dial and mirrored the design of contemporary painted dial longcases, they date from towards the end of the 18th C and afaik did not have applied spandrels. The corner ones on this dial are ill fitting and of a much earlier design and along with arch ones are imo a later addition.
Loomes has John and Thomas Perigal and Perigal Brothers listed at Coventry Street. Details are; John 1770, CC 1781-1800. Partner with Masquerier 1772-1782 then with Browne to 1799. Thomas 1784, Brothers 1772.
There are quite a few makers called Perigal listed in London, they appear to be French Huguenot refugees and their descendants.
