Bought my first Remy 1903, help with identification?

[SemperFi752]

Hi all! I am brand new to the board here, and pretty new to pre-60's firearms. Recently, I decided that I was getting bored with the new age stuff and decided to take a step back in time. Starting with a No4 mk2, I then gave a new home to a 8-42 Winchester M1, and just yesterday I plucked up this 6-42 Remington 1903. I have been looking for quite some time and passed on many rifles before buying this last night at Cabela's. I typically do not buy things from big box stores in order to procure the best deal, but this one just felt right. The tag was labeled $799, but I asked if they could wiggle on price, and they took it down to $729. I would like to know if I got ripped off, but I was just excited to have a 1903 built 2 months prior to my M1.

I have taken 18 pics to show markings that I have found. My primary concerns are as follows:

-The stock shows only 1 marking, in the magazine cutoff selector cutout, there is a K. The top front wood is cracked as well. I don't think Remington shipped with this style of stock (pistol grip) in 1942?
-The firing pin/bolt. The knurling does not appear to be Remington?
-The sling. It appears to say R M co. 1942/3?
-The sight. Is this original for this time period?

Anything and everything you can tell me about this rifle would be so appreciated, including if this was a decent deal. I am going to take her out the desert today and put a couple rounds downrange and could not be more excited. The bore looks great to me and appears to be the original barrel.
