Here is a gunboards post indicating the prior to the 19 model, Mexico bought some in 1899 in 7mm Mauser. From gunboards, "The "Us" on the barrel bands should have the open side of the letter U facing toward the muzzle and be on the left side of the rifle when you reassemble the piece. The U on the band tells you which side of the band is supposed to be pointing toward the bore as you can install them backwards. I also suspect that it would have been more like 1894 or so before Remington came out with a 7mm Mauser as the Spanish did not formally accept the cartridge until 1893 from my understanding (the older Spanish Mausers were to test the concept and are very rare). Now I have another rifle without a plaque with a serial number in the 1400's. Remington, USA: 10,000 rifles Norway: 53,450 rifles (of which 5,000 were later converted to carbines) Sweden: 237,000-257,000 rifles and carbines, including conversions of older rifles to rolling block. I think it is safe to assume that the rifle was made sometime in 1879 or no earlier then 1878. Block for these rifles and possible future orders was 4922001-5784000. The serial number is in the low 3,000 range. You might try Gunboards to get a bit more precise date as some subforums of that board have stickies with serial number information. note: before 1865, serial numbers were not given to National Armory weapons. Assuming it was not rechambered, the 7 mm Mauser cartridge dates from 1892 which puts it ten years from 1902 and you know it is not an 1901 or 1902.
