Barrel dated 3-43 4 groove. Parts blued where there supposed to be. Right F.J.A. stock appears unmolested. . When did they go 2 groove. Is this a early Remington. Thanks in advance.

Kinda early. 332xxxx were the first A3's. Looking at the VIshooter site, 2 groove barrels started to appear in production around the same time your rifle was produced.
