MG51: When the Swiss Make an MG42

When Switzerland decided to adopt a modern universal machine gun toe replace both the MG11 Maxim and the LMG25, both SIG and Waffenfabrik Bern used the German MG42 as a starting point. W+F Bern was the eventual winning of the trials with the MG51. This is basically a Swiss out-Germaning of the Germans. The stamped receiver was replaced by a milled one, the barrel made heavier for more sustained fire, and an effective anti-bounce system added to prevent the out-of-battery discharges that were a problem with the MG42. A number of other minor improvements were made as well.
