Rock Island 1915 Stamped Stock

[John Beard]

While I suppose it's possible, it's very highly unlikely authentic. According to my extensive data bases, the last pre-WWI stamps were dated 1913 and the earliest WWI stamps were dated 1917. Rock Island resumed making rifle parts in late 1916 in anticipation of U.S. entry into WWI.

If the rifle sitting in the stock is an RIA, please oblige us with the serial number and barrel date. Also, is the stock marked beneath the wrist with an encircled "P" proof mark and is the "P" a script letter or a block letter? Also, does the stock have any markings in the cutoff recess and, if so, please describe. And what marking, if any, appears on the stock fore end tip?
