WThe Farquharson Rifle is a single-shot hammerless falling-block action rifle designed and patented by John Farquharson, of Daldhu, Scotland in 1872. George Gibbs, a gun maker in Bristol, became a co-owner of the Farquharson patent in 1875 and was the sole maker of Farquharson rifles until the patent expired. Fewer than 1,000 Gibbs-Farquharson rifles were made, the last one being delivered in 1910.
WThe M1870 Belgian Comblain was a falling-block rifle invented by Hubert-Joseph Comblain of Liège, Belgium and produced in several variants known as the Brazilian, Chilean or Belgian Comblain.
WThe Ruger No. 1 is a single-shot rifle with a Farquharson-style hammerless falling-block action, introduced and manufactured by Sturm, Ruger & Co. since 1967. An underlever lowers the breechblock to allow ammunition loading and also cocks the rifle. Lenard Brownell, commenting on his work at Ruger, said of the No. 1: "There was never any question about the strength of the action. I remember, in testing it, how much trouble I had trying to tear it up. In fact, I never did manage to blow one apart."
WSharps rifles are a series of large-bore, single-shot, falling-block, breech-loading rifles, beginning with a design by Christian Sharps in 1848, and ceasing production in 1881. They were renowned for long-range accuracy. By 1874 the rifle was available in a variety of calibers, and it was one of the few designs successfully to be adapted to metallic cartridge use. The Sharps rifles became icons of the American Old West due to their appearances in many Western-genre films and books. Perhaps as a result, several rifle companies offer reproductions of the Sharps rifle.
WThe Sharps-Borchardt Model 1878 is a single-shot hammerless falling-block action rifle designed by Hugo Borchardt and made by the Sharps Rifle Manufacturing Company. It closely resembles older Sharps Rifles but has a firing mechanism that uses a hammerless striker rather than a hammer and firing pin like the old Sharps Rifle. This hammerless dropping-block breech-loader was based on a patent granted to Hugo Borchardt in 1877. It was the last of the Sharps single-shot rifles, and the Borchardt did not sell very well. According to company records 22,500 rifles were made in all models from 1877 until the Sharps Rifle Co. closed down in 1881. Although it was designed for the huge black powder "buffalo" cartridges of the day, it came too late, at the very end of the great bison slaughter.
WThe Starr carbine was a breechloading single-shot rifle used by the United States Army. Designed in 1858, the Starr was primarily used by cavalry soldiers in the American Civil War.
WThe Winchester Model 1885 is a single-shot rifle with a falling-block action. It was principally designed by John Browning. Two models were produced, the Low Wall and the High Wall.
