Many of the terms used about these Britishsmall arms were American terms invented (by Sam Cummings?) in the 1950s/60s in order to sell more surplus guns to Americans. Some like "Jungle Carbine" have stuck whereas other such as "Tankers Model" for the Revolver No.2 Mk.1*/** have (mercifully) not. Most of the terms are not only made up but inaccurate (e.g Royal Enfield when referring to a rifle, rather than a motorbike.) and so I believe that those of us who take our history seriously should be researching this stuff and "showing it up" - as my mother would have said.
BTW, I am of Irish decent and I think I would have noticed if anyone had been offensive.
