British small arms.
A bunch of rifles, machine guns, handguns, et cetera from the United Kingdom. There’s actually one gun in there which has left me absolutely stumped - the “Edgecumb Arms Combat Ten”. Googling it brings up no relevant information (apart from a wikia page which I wrote). Otherwise I’ve been able to trace information on every weapon here.
