My first M1!

[alktrio06]

Ha, wow! This is a bit overwhelming.
I found a Saginaw bolt on ebay...
M1 Carbine Saginaw undated Barrel Complete | eBay
Looks legit as they did not date their barrells.
I like the idea of switching out stocks to keep the rare one safe. How much is it worth by the way? The serial # for my M1 is 3445269.
There are two stocks on ebay currently...
M1 CARBINE USGI WWII ORIGNAL SAGINAW GEAR S.G. STOCK | eBay
M1 CARBINE USGIWWII ORIGNAL SAGINAW S'G' STOCK HIGHWOOD | eBay

Here is a hand guard as well...
M1 Carbine Saginaw Type II Handguard RSG | eBay
Or would this be more appropriate?
M1 CARBINE HANDGUARD "IO" 2 RIVETS WIDE GROOVE NICE, INLAND | eBay

To address your other comments, as you said the serial number will dictate those. In terms of the internals, I am not concerned with those. Although, I will take it part this week and post pics and see what you guys think.

I apologize for all of the questions! I really thank you for your help. I should consider joining the Carbine club.
