I cover this area from mid-18th century to late-19th century, from flintlock to early cartridge guns. For me this is where hobby and profession meet, as I'm a black powder enthusiast (ex-fencer)! My particular interest is in American and British revolvers of the percussion era and, to a more general extent, in British and European service handguns from the 19th century. Good reference books include: English pistols and revolvers by J N George; Howard Blackmore's book on English service firearms of the 18th & 19th century. Museums with important collections include: the Royal Armouries, Leeds; the Wallace Collection, Manchester Square, London W1; Musee de l'Armee, Paris; the Metropolitan Museum, New York; Heeresgeschichtliches Museum, Vienna; and various other museums in European capitals.
