Colt 1911 Barrel

[bill2]

I have stumbled onto a Colt 1911 Barrel with a boxed C on the left lug along with the proof P. I have checked book and forum and found no info on a barrel with Boxed C on left side markings.
Can anyone advise of this barrel application, Manufacture dates , date of pistol used in? All help appreciated. PM or email is fine.

Are those the only markings? If so, it's a very late WWII (mid-1945) GI barrel. If it also has Colt 45 Auto on it, it's a post war barrel. I've been looking for one of the former for a while, especially one with original blue.

To clarify, .....if it has "Colt 45 Auto " on the top of the chamber, (visible through the ejection port), then it's post war.

If the "Colt 45 Auto" is on the lower side of the chamber, boxed-C on the leg, then its mid 1945.

Pictures of all marks please.

Per Charles Clawson
Boxed in C
This was a post war replacement Barrel used on pistol barrel replacement till the army used up all the inventory.

What is hard or what we don’t know how many the army bought from colt but I guess they didn’t have a need after 1946.

One other point that I am not sure is after WW2 if Springfield armory didn’t reset of their barrel making machines after getting them back from Flannery Bolt. After WW2

Correct, thank you. I meant to type "Colt 45 Auto on top" not "on it". I have seen a couple wartime barrels without the Colt 445 Auto on the side though. The marking on top of the chamber is a dead giveaway for post war.
