The Colt New Service model was the largest swingout-cylinder revolver made by Colt and appeared in 1898 and continued with various improvements and modifications, until 1944. Due to the period of its run, the model saw service in both World Wars and was produced in eighteen calibres, including popular British calibres to cater for that market. This particular model is stamped with British ordnance marks and chambered to the popular English .455 Eley. Army and Navy models were produced in 1909 and in the same year a now rare to find Marine Corp model was produced. One of the best known variants is the 1917 model chambered to .45 ACP, three rounds being held in a semi-circular clip for speed loading. Two clips loaded the cylinder. The same ammunition could also be used in Colt's 1911 automatic pistol.
