This Colt 455 Webley was shipped to the London Armoury Company of 31 Bury Street, S.W. 1, London, England on July 19th, 1915 in a 200 gun shipment.
The right side of this pistol is marked "T.H. Hill, 14th Battll. Worcester Regiment."
This particular pistol shows the British proof marks on the left hand side which was common practice for all firearms that were imported into the country during this period. This pistol also has the "JJ" mark on the left side of the dust cover.
The JJ mark was stamped by James Joseph Goodbody between 1911 and 1913 when he ran Colt's London Agency. The Agency closed in 1913 but the London Armoury Co became Colt's exclusive distributor in England and they continued to use the same stamp until about 1930. This was to avoid warrantee responsibility for guns that were not sold through them. Colt's that went to England through other channels (military or private imports) will not have the JJ stamp.
