Today I am joined for a round table discussion (well, octagon table, technically) by Jonathan Ferguson (Curator of the National Firearms Centre collection at the Royal Armouries) and Nic Jenzen-Jones (Director of Armament Research Services) to discuss a variety of improvised and craft-produced firearms. All three of us are contributors to a research paper being published by the Small Arms Survey on this subject, and we thought we would take a few minutes to discuss it on video.
