After World War Two the Swiss needed a new self-loading military rifle to replace their K-31 bolt actions. Two major design tracks followed; one being a roller-delayed system based on the G3 at SIG and the other being a derivative of the German FG-42 at Waffenfabrik Bern. Bern, under the direction of Adolph Furrer, had been experimenting with intermediate cartridges since the 1920s, and they used this as a basis to develop an improved FG-42 using an intermediate cartridge (7.5x38mm). The program began in 1951 and went through about a half dozen major iterations until it ultimately lost to the SIG program (which produced the Stgw-57).
Today we are looking at one of the first steps in the Bern program, the WF-51. The most substantial change form the FG42 design here is the use of a tilting bolt instead of a rotating bolt like the Germans used. It is a beautifully manufactured firearm, and a real pleasure to take a look at...
Many thanks to the Royal Armouries for allowing me to film and disassemble this rifle! The NFC collection there - perhaps the best military small arms collection in Western Europe - is available by appointment to researchers:
