It is a Webley made pistol patented by C Pryse in November 1876. It is sometimes called the 'Chinese Webley' due to the fact that the Chinese Government bought large quantities. This American large calibre, heavy duty holster arm was specially designed for military and constabularv organisations. It was in production from 1897 to 1943 and was known as the 'New Service' model. This model began the development of the modern Colt rebounding hammer.
Notable differences are shorter barrel, no trigger guard, folding trigger.
Both the models are six-chambered, double and single action of the Chamelot Delvigne design. This French revolver made in St Etienne, was a common souvenir among US troops returning from World War 2. Some of these models were modified to use the 8 mm cartridge, but as originally issued they were designed for use with a low pressure, black powder cartridge which was made in France only and should not be used with any other cartridge. In the 1880s, revolvers were produced based on the Webley designed pocket revolver known as 'The British Bulldog'. Originally these revolvers were of a large calibre of 9-11 mm.
