Anyone recognize this barrel stamp?

[RCS]

Back around 2007, my friend called me from a Georgia gun show, he said he found a SA 1903 from 1918 with a stock marked TENN, rifle was sold from the CMP, asked if he should buy it for me. I said ok.

My SA is serial number 825055 with Hatcher hole and SA 3-18 dated barrel and the "Greek barrel stamp" under the barrel like yours. It is a Greek stamp. Both your rifle and mine both fall into the US Navy/USMC serial ranges. My stock is marked W.E.S. and BA JS plus TENNAttachment 107232Attachment 107233
