Good afternoon! I recently came into possession of what I believe to be a 1916 Number 1 Mark 3 manufactured by Cogswell and Harrison. http://i.imgur.com/KGtEdB7.jpg Ain't she a beauty? It doesn't have the blunderbuss-like thing at the end (which, if I recall, was added due to burns? I guess i'd better get Nomex gloves). According to my (admittedly very cheap) electronic calipers, it's in roughly 26.5mm (which is a bit bigger than the listed 1" caliber), can I fire regular 26.5mm flares and rocket flares out of it? If not, what ammunition can I fire out of it and where should I look for that ammunition? Additionally, anybody have a guess at what it's worth? Cheers! -J
