Your Remington Rand went through an arsenal overhaul at Springfield Armory. There is no way the current barrel is original to your pistol. Some Colt and SA barrels were used in very early production, but they would have been gone by the time your pistol was assembled. Checkered mainspring housings were used into the latter part of 1943, so that was added sometime later as well.
