numbered 124 (indicating a purchase and issue of at least 124 of the rifles), also has a replaceable chamber section. The replaceable chamber makes this example both a breechloader, and effectively gives it a seven shot replaceable magazine. It is not known if multiple magazines were issued per gun, though this was possible (see here for a similar scenario with percussion revolvers). The lock slides from front to rear, with a second trigger provided that slides the lock from touch hole to touch hole, allowing each successive charge to be ignited. The lock did require cocking and priming between shots; while this would take time, the sliding lock would have provided a much higher rate of fire over a typical single shot musket of the era. The Belton sliding lock design was later improved and used in slightly more successful designs, such as Isaiah Jenning's repeating flintlock rifle. Four shot pistol design Today there are two surviving Belton and Jover pistols at the Pitt Rivers Museum at the University of Oxford, having four touch holes which permit four successive discharges.
