Hi Davebone,
As I wrote previously, surplus Brown Besses were not popular except as sources of scrap. Their weight, big bore, and slow locks made them lousy sporting guns. The Brits palmed many off to Mexico as muskets in the 19th century but not for civilian purposes. British ordnance struggled to find buyers of surplus Besses and most went for little money as scrap. That fact presented British ordnance with a serious dilemma. They needed to keep tradesmen employed in the gun trade as a measure for national security. That way they always had the supply of skilled workman ready to make muskets when war threatened rather than having them melt away into other trades during times of peace. However, they could not afford to make endless supplies of arms that were not needed and they knew that those excess arms would be worthless in a very short time. An alternative was to encourage involvement of the gun trade during times of peace in places like Africa where firearms were the currency for gold, ivory, and slaves. Slaves mainly for British sugar plantations in the West Indies that were the source of great wealth in England. This was a major market for British gun makers when government ordnance contracts were scarce. The East India Company was another avenue. So the British government constantly had to juggle small arms production during the 18th century to assure it could produce the arms when needed and without a huge and expensive government manufactory like the French. This is also why British Ordnance insisted on issuing older patterns of the Brown Bess musket before supplying newer and updated patterns. They knew that if they moved immediately to issue the new guns, the old ones would be worthless because they had little surplus value and an expensive loss to the government.
