A patent of the Landstad revolver, filed on the 11th of April, 1899
|Place of origin||Norway|
|Cartridge||7.5mm 1882 Ordnance|
|Feed system||Single-stack, single-row-feed magazine|
It was chambered for the 7.5mm Nagant cartridge, which at the time of the creation of the Landstad was also used in the Swedish Mod. 1887 and Norwegian Mod. 1893 Nagant revolvers.
The revolver design was patented in 1899 by Halvard Landstad, from Kristiana (now known as Oslo). Landstad designed the revolver with his own money and presented it to military trials in 1901. The gun never went into production because the revolver failed in the trials, but the inventor kept a prototype of the gun. It was donated to the British NRA after the inventor's death in 1955. In 1977 the revolver was sold in an auction.
