Almost looks like a Kit Ravenshear creation. We made barrels for Kit to build a Nock "Volley Gun". It was a seven barreled gun, however, the barrels did not revolve. When you fired it, the pan fired the middle barrel, and the outer
six barrels were vented from the middle barrel, so that all seven went off at one time. They were all 50 cal. barrels,
and if I remember correctly he shot about 20 grains in each barrel, which equates to 140 grains of powder, but this was
pushing 7 - .490 balls @ 180 grains each, or a total of 1260 grains of lead going out the barrels at one time. We fired
it several times, recoil was not bad, and it kept all seven balls in about a one foot circle at 25 yards. It was kind of a
neat gun, and I am not sure who owns it now........Don
