Picked this one up about a month ago, been waiting for the weather and less work to tale some pics. The serial number puts it around august 1954 for manufacture. It's a CMP (Civilian Marksmanship Program) rifle, so it's not all matching. The bolt and internals are Springfield Armory, except for the op rod, which is HRA marked. No cartouches left on the stock.
