American 1871 Patent .38 Rim Fire Calibre Nickel Plated 5 Shot 'Swamp Angel' Single Action Revolver (Named After An American Civil War Cannon) By Forehand & Wadsworth Worcester Mass USA. Sn 11762. - 11762This is an original example of the .38 RF Calibre "Swamp Angel" Revolver built by the U.S Gun manufacturer Forehand & Wadsworth in the 1870's. The name SWAMP ANGEL was derived from a powerful Civil War cannon. The Swamp Angel was the nickname given to a 16,500 pound rifled Parrott cannon with an eight-inch bore that briefly shelled the city of Charleston in August 1863. The massive gun was positioned near Morris Island in an earthwork made of sandbags known as the Marsh Battery. The construction of the Marsh Battery, which virtually floated on the marsh, was considered to be one of the greatest engineering feats of the war (the company co-owner was a Union Army Officer during the Civil War). The pistol has a 3" barrel and measures 7" overall. It has undamaged walnut grips and the metal retains much of its original nickel plating with small areas of staining consistent with age. This 5 shot revolver has a shrouded trigger and the left side of its octagonal barrel is marked with the Forehand & Wadsworth name together with 'Worcester Mass U.S.' address & ‘Pat Sept 24 Oct 22/61- 31 Jany 27 71’ patent detail. The top of the cylinder frame is crisply marked with the ' Swamp Angel' model detail (illustrated). It has a blade foresight & notch rear sight. The single action cocking and firing action works perfectly. Price for this revolver with connection to the American Civil war includes UK delivery. NB As an obsolete calibre revolver no licence is required to own this item in the UK if retained as part of a collection or display. Sn 11762.
