Questions on first M1

[Bruw]

OK, so I've fallen head over heels for the M1. I know, just like most everyone else around here. I've been reading everything I can find on it both in print and on the interwebs, but still have some questions about my first M1. It is a service grade Springfield from CMP, serial #4288***. I'll attach some pictures below but here are some of my questions. I've been using the USRifleCal30M1.com website to date certain parts. How accurate is that site? If I'm reading it correctly, I have parts on my rifle from 52 to 54ish, and apparently the receiver itself is the newest part on the rifle. All parts I have identified are SA, and seem to be original, with the exception of the trigger guard which is WRA with the extra loop in the back. Barrel measured 2 ME and 3 TE which seems really good for what I think is an original barrel, since it is stamped 11-53. Anyway, I'll post pics below and if I am misinterpreting info or if there are better reference sites for dating parts, I would welcome the education. Thanks!

and a few of the stock...

Op rod was used on rifles in 1943, stock looks to be HRA. Nice rifle

The -6 op rod is also correct for late 42 m1's like mine that I'm trying to find.

Wow!! You did well!! GI wood is a bonus!!

A 4.2 mil SA is a great one to get. Built for Korea, that is a nice HRA stock. Mixmaster of other parts. Post war rifles are much easier to restore than their war time brothers if that is even an avenue you want to pursue.

Thanks. What identifies it as an HRA stock?

[Tothemax]

Cartouches.

[Bruw]

Is it reasonable to assume that the barrel is original? How would you determine that?

More specifically, the 1/2" DAS (on the left side) and the non-serifed proof "P" on the pistol grip.

The shape of the grip, the stock comb, and the heel at the rear of the rec'v'r is also somewhat distinctive of HRA stocks.

That's a really nice rifle, congrats.
