I recently purchased a 1945 M14 1911 Norwegian Colt. The outside of the pistol has all matching numbers on everything but the hammer and the barrel bushing. The only part on the inside numbered is the barrel. Is it possible it was put together this way?, all the earlier one's I have seen have all matching numbers on all the parts except the spring on the inside. I can't find any info that explains pistols put together from 1945-1947. Any info would be appreciated. Bill
