From my limited knowledge, it seems that the major western armies were working to phase out matchlocks in place of flintlocks by the late 17th century. However, given the distance between the Americas and the countries that colonised them, and the remote nature of some of the settlements there, I was wondering how much recorded military or civilian use there was of matchlocks across North and South America after 1700? It would be interesting to see how late these weapons endured in practical use after that date.
