Colt M1911 Barrel Identification Help

This barrel was installed in a Colt M1911, serial number 309XXX. All other parts and markings appear to be correct for the pistol but this barrel is marked in a way that I have not seen in any publication. No other marks or stamps were found on the barrel.

not sure if it helps, but this is the only thing I've found so far. haven't found any info on the "R" yet. Is there an "S" or a sideways "H" on the top rear of the barrel hood like the one in the illustration?

hmmm... The "P" has got to be a proof mark. According to the Poyer book (Pg. 355) the first 1,000 Remington Rands had the "P" proof mark in that location. I haven't seen anything about the "R" yet. I will continue to see what I can find.

There is another "R" marked barrel (similar to this one) and also (apparently) associated with a 1918 M1911. (And another without the "P" on top of the chamber.)

Are there any marks associated with an Arsenal on the receiver like RIA, AA, MR, etc? Is the rest of the gun original in finish?

Would like to see quality pictures of the back of the barrel hood, back of lug, and bottom in front of lug. Left and right of the gun, and top of receiver around disconnector hole.

I also have a barrel with these stamps and wouldn't mind knowing the story behind them or what 1911 they are correct for.

There are no marks/stamps anywhere else on the barrel.

Off topic but the RR MSH was perfect for my need. Greatly appreciated.

Plywoodking,

Is your barrel associated with a Pistol? Is this your picture (or do you have pictures of your barrel)?

Here's an old internet picture of another "R" and "P" marked barrel (and apparently also associated with a 1918 M1911 Pistol).

Best Regards,

Here's internet pictures of the other "R" marked barrel. Apparently, it does not have a "P" on top of the chamber.

I don't know the story behind these barrels either but I also have one. Looking at Clawson's commerical book (pg 211) Clawson stated that in 1916 at around serial number C30000 (1st qtr 1916?), the "P" was moved from the top of the barrel to the bottom along with an inspector's mark. This continued to around serial number C101000 (mid 1918?). Could these barrel with the P and R stamp on the top be from early 1916? Possibly 1915? Just trying to figure this stamp out as well. Anyone with a 1915 or 1916 (pre C30000 serial number) confirm the barrel in their pistol with this information?

This gun with an R marked barrel popped up on P98 a few days ago:
