Perhaps a mis-reading of information?
I believe there are no markings on the rifle. No need to tear the rifle down as the current owner purchased it in pieces and he mentioned he spent about 80 hours getting it into the shape it is in. Were there any markings he would have found them.
I had a phone conversation with the present owner shortly after this thread appeared. A very pleasant and entertaining gentleman.
The 80 hours referred to was time he spent in looking at the rifle, figuring out how it worked, doing some adjustments, and trying to convince the Bureau of Alcohol, Tobaco and Firearms that it was actually a SEMI automatic rifle, and not a machine gun. In doing so, he rescued an interesting rifle from certain destruction.
So, he actually did not spend 80 hours getting it into the shape it is in.
We also have to remember that during the time the United States entered WW1, they were desperately short of Military rifles. 20,000 1905 Ross Military Mark II rifles were purchased from the Ross Rifle Factory. The remainder of the 280,000 Remington made M-91 Mosin Nagants were purchased when Russia backed out of the 1915 Contract. The serviceable remnants of 160,000 Krags, and a number of "French" rifles were used. Beginning in 1919, these rifles, along with excess M1903 Springfields and M1917 Enfields were sold off to the Civilian public. (Krags were $6.19 for an unissued one, $16.17 for a Springfield and $30.00 for an Enfield. Enfield prices were later reduced to $15.00 and then to $7.50.)
Between 1920 to 1940, Springfield Armory was still tooled up for the M1903 Springfield, and produced 2500 M-1903 Sporters and 26,000 National Match rifles. You could buy a new National Match Rifle for $53.10 in 1936.
In 1918, the Browning Automatic Rifle had been adopted, and Savage was already making a Machine Gun, the Lewis in 30-06, so they were familiar with gas operated weapons.
From the mid-1920s Pedersen and Garand were working on gas operated semi-automatic rifles, and in the 1930s, Johnson developed his semi-auto rifle that used the long recoil system. These rifles weigh approximately 10 pounds, so a 16 pound semi auto rifle holding only 5 rounds would be redundant as a viable military rifle.
Also, the fact that the trigger is aproximately 3 inches forward of the pistol grip makes me wonder. Savage had several years producing sporting rifles, the 1899 being an in production model. Their engineers would be very familiar with the ergonomics of handling, fit, comfort and utility of a rifle stock and trigger relationship. Ross had developed the bolt action Sporters and target rifles, so he knew just what a stock should be designed like. The idea of a 16 pound Sporter is almost ridiculous.
The Ross Factory was taken over by the Canadian Government in 1917, and Ross had little to do with the manufacture of Ross Rifles from there on. The last 260 HG rifles were made after Ross had been forced out, and the Mark III Ross was considered a more-or-less up to date rifle.
Like SMELLIE, I would love to find the answers to many questions about this rifle, if only from a historical or curiosity point of view. But, many things do not seem to make sense, or "fit."
