Nice little rifle! I remember an effort to really produce and market the P.O. Ackley rifles approx. 1970. The gunshop I grew up in received two for inventory, a .30/06 and a .270. I think the owner actually became what amounted to a dealer, and I remember putting a P.O. Ackley decal on the front door. The decal was a graphic of a barrel bore and rifling. These may have been Santa Barbara actions, I do remember the sliding safety, and they were drilled & tapped. Your rifle is for sure earlier than that. I like it.
