54-Bore (.442). 6" octagonal barrel length. SN: 16813R / B812. Blued finish, color casehardened 5-chambered cylinder, checkered one-piece walnut grip. Top strap and top flat of barrel engraved in a single line: "Deane, Adams & Deane No 30 King William Street London Bridge" with lower right side of frame engraved in two lines: "B. 812 / Adams' Patent No 16,813R". Cylinder with matching "16,813R" serial number engraved as well. The "B" number indicates this is the 812th revolver produced under the Beaumont patent improvements. Barrel and cylinder with London commercial proof marks. The assembly number "2497" if found on the reverse of the loading lever, rear face of cylinder and inside triggerguard. Frame engraved with tight foliate scrolls, with butt cap engraved en-suite as well as forcing cone area of the barrel. A very interesting transitional Beaumont-Adams revolver that includes uncommon features for a Model 1854 revolver. Despite using the "Beaumont" lock improvements with the hammer spur, the revolver remains a double-action only gun with the older Model 1851 patent spring safety on the left side of the frame which is engaged to achieve the "half-cock" position. However the cylinder arbor pin is retained by the newer M1854 patent thumb screw, and the M1854 patent sliding safety that blocks cylinder rotation is found on the right side of the frame as well. The grip incorporates a concealed cap box in the butt, a feature typical of the M1851 revolvers but not normally found on the M1854 guns and also has the flared base of the M1851 guns, but with the M1854 grip angle. The revolver also incorporates the relatively scarce Rigby patent ramrod that is stored by folding it into the grip area. This rammer was used prior to adopting the more common Kerr patent design and is typically associated with the early M1854 Beaumont-Adams revolvers produced at London Armoury Company when Adams went to work there in 1857. While Adams revolvers cannot be easily dated based upon serial number, the presence of the post-1854 patent features, the Deane, Adams & Deane markings, very low Beaumont patent tracking number and the fact that Adams had moved to the London Armoury Company by early 1857 suggest this transitional revolver was produced circa 1855. Revolver is contained in a typical compartmentalized English oak casing with recessed lock and brass Bible hinges with a dark green baize lining and a reproduction Adams retailer label. Accessories include a correctly marked Adams Patent dual conical cavity 54-Bore bullet mold, a James Dixon & Sons marked copper bag shaped pistol flask, a rosewood cleaning rod with removable brass jag and concealed ball puller, an unmarked pewter oiler, an embossed japanned tin Eley brother tin of caps, a reproduction ebony handled cone wrench with cone prick in bottom and a rosewood handled turnscrew. A fine and interesting transitional Beaumont Adams revolver produced towards the end of Robert Adams' tenure at Deane, Adams & Deane.
Fine. Revolver retains most of the blued finish with minute traces of case color on the face of the cylinder. Cylinder with a mostly pewter patina. Metal mostly smooth with some flecks of oxidized surface roughness on the cylinder and some scattered pinpricking. All markings remain clear and crisp as is the engraving. Mechanically functional, double action only as noted above. Fine bore with some scattered oxidation and fine rifling. Grip with some light wear and handling marks. Casing about good to very good with wear, scuffs and mars. Lock missing escutcheon on face of case, interior with moderate wear, some damage to the dividers and some loss to the lining, which shows substantial fading. Paper label in lid a poor quality reproduction.
