gunsmiths is a significant source of illicit small arms in some areas. A recent study of craft production in Ghana by Emmanuel Kwesi Aning found that the country’s unlicensed gunsmiths have the collective capacity to produce up to 200,000 firearms a
year, some of which are reportedly “of a quality comparable with industrially produced guns”.
