This was a design by Josef Schulhof (1824 – 1890), gunmaker from Vienna. He patented a repeating rifle in 1882 and was credited with having developed several types of repeating pistols around 1884. All required a manual movement to chamber and discharge the cartridge. Sometimes, both actions were performed simultaneously. The finger loop lever under the receiver was used to close the bolt. Having travelled to its final position, the trigger could be pulled to release the firing pin. These repeating pistols were complex and cumbersome but considered the foundation in the development of semi-automatic handguns. According to Rock Island Auction fewer than 50 of these pistols were ever manufactured and the highest known serial number up to now is 36. (Erlmeier, Brandt Ref. 155).
