I have a Rem Rand M1911A1. As far as I can tell, it's correct, or mostly so. On one side of the barrel lug is the proof '' P''. On the other side of the lug is the letter '' F''. Who made this barrel and what is the chance it's original to the gun? I don't have the s/n handy but it is a May '44 produced gun.
Thanks
Jon
