Question about proper barrel

[James in NC]

Guys I have a WWII Colt serial # 903385. What markings would the correct barrel have. I have looked at CoolGunsite but am still a little confused. The barrel in it is marked 'Colt 45 Auto' on the left side above the lug. There is a 'P' on the left side of the lug. And under the barrel is a small 'F' with a big 'G' underneath it. Is this correct? Any info would be appreciated. Thanks James,

I'd say you're fine. If you look at photo's 11 & 12 on http://www.coolgunsite.com/ barrel ID page, it looks like you're SN is right there in the cutoff SN's. You just got both stamps.
