I attach a photograph of the hallmark on a recently purchased watch.
The Chester hallmark ‘q’ is I believe for 1879 and on another element of the watch there is a ‘p’ in the same font.
I an having difficulty identifying the maker from the indistinct hallmark. The first two letters are ‘W.G.’ followed by a poorly defined letter which might be ‘H’. I have found WGH - without the ‘.’ corresponding to William George Hammon of Coventry registered 4/1875.
Grateful for any assistance.
