In 3006 cal. Looks like a M1917 if 3006 (p17) or if 303cal (p14) Eddystone ,Winchester or REM manufactured. Gotta cal on the barrel ora date? Opps, I took a second look and notice the barrel is missing. Looks like an Eddystone to me that was sporterized after the war for sale to the public. Some had the peep sight ears milled off to accommodate open V notch type sights. It does not have the full wooden stock.
