http://www.forgottenweapons.com This happened to be at a shoot I attended recently - the prototype for a commercial reproduction of a 3-barreled Nordenfelt. These were competitors to the Gatling (along with the Gardner) and eventually the early Maxims. This one is chambered in .45-70. Pushing the lever forward fires the three barrels sequentially, although so close together that is sounds like one shot. Because they are sequential and not simultaneous, it's not an NFA item. I don't know when they will be available for sale or who the distributor will be, but it's neat to see someone actually making Nordenfelts. The originals included variants with anywhere from 1 to 5 barrels, in calibers up to 37mm.
