The reason I use the Tranter name is that its an old English gun company I once worked for. William Tranter himself made guns from the 1850s and one of the most innovative might interest some of you. The double trigger revolver. The lower trigger cocks the action and the upper drops the hammer. So for single action fire, pull the lower only, then the upper when ready. For double action rapid fire, just pull both together. It sounds a lot harder than it is. H&K even adopted the principle for their P7 with a squeeze cocking front strap. Hm. The British percussion revolvers of the period were more robust than the American ones, note the sold frame and barrel. Also the thoughtful hump at the top of the backstrap to stop the weapon riding up. Just thought it might be of interest..
