Now things are beginning to fall into some kind of line.
British rifles were, of course, marked on the metal, while Canada had them marked on the wood. Rosses, of course, had no "disc, marking, butt" but they had to be marked somewhere, so right on that otherwise-blank part of the receiver ring would seem a good location. When they went into British Service, it only makes sense that they would be numbered on the metal... and right under the formation stamp would seem a likely spot. It's logical, anyway.
And now that letter from the Royal Marine Museum. Ah, that letter! Great work, Gallen!
A large force such as the Royal Marines also would demand quite a few rifles, clearing up the mystery of the serial numbers, which indicate a spread, just in the 3 rifles here, of more than 2,300 rifles. Apart from me, there likely aren't too many people who would want 2300-odd identical Ross Rifles, so we must be looking for a military formation and this one seems a likely bet. Just the list of British warships by name alone in that War runs to pages and pages and pages... and every one of them would have had some sort of Royal Marine presence, one would have thought. There certainly is ample room for 6009 rifle, more of less, much less the 2315 which we are pretty certain existed.
As to ragged stampings, it was wartime, manpower was short, and I can hardly think of a much more onerous job than stamping serial numbers on several truckloads of rifles and doing it RIGHT NOW, YOU UGLY LITTLE MAGGOT! (This roared by the RSM, of course, as he calmly eats another baby.) I would think that very tired men, working at top speed hour after hour, just might get their stamps a bit out of alignment. Today, 95 years later, it is proof to us of how overworked and tired they really were in those desperate days.
Add to this friend Buffdog's all-night Internet research, turning up another 14 references, and we are beginning to have some kind of idea as to the survival rates of these historic old pieces. All we need right now is a decent U-boat so our rifles have something to sneer at as they sit on their racks, quietly mulling over the 'good old days' when they were policing the sea-lanes of the world.
Makes one think.
A suggestion from Buffdog (via telephone, just in the last few minutes) now has me checking Naval possibilities regarding the matched pair of 'stripped' Rosses I have here, prominently stamped PHAB 1 and PHAB 2 respectively. Harbour Artillery?
Find out!
Gotta go!
