Colt/NAC5 has no ground numbers or symbols. The receiver markings are all as Colt did them except for the rounding done by polishing for bluing. It is not a complete Colt finished gun.

As we know, the Auto-Ordnance assets changed hands several times. In 1949 Maguire sold all the known assets to Kilgore who then sold to F.A.Willis. In 1951 Willis sold the whole package to Numrich. It has been said that no one ever looked in the cases during any of these exchanges. Numrich acquired and promptly registered the guns found in the cases. This created a regulatory firestorm.

The Numrich records show the following on an inventory index card Thompson 1921 .45 NAC acquired from Fred A. Willis, 1 December 1951. That same card then shows the gun sold to the Virginia State Police on 5 June 1953. Then the Virginia State Police sold it to Curtis Earl on 3 September 1974. I acquired the gun on 14 October 1981. The Numrich data is on a copy of the inventory card. I do not have a copy of any transfer/tax document. The Numrich information was obtained for me by a friend from either George Numrich or Ira Trast during the 1980s. The later data was provided by Curtis Earl.

So what do we have here?  Helmer on page 206 says 86 complete guns were in the crates Numrich obtained and subsequently registered. Cox states on page 3 in his book that 200 guns were present. What we do not know is how many of these guns were really complete and how many were finished receivers. We only know that the government settled for $12,000.00 when the whole batch was registered. In any event, maybe it was 86 and maybe it was 200 and what does complete mean in this context. Were there any "complete" Colt guns? On the face of what I have seen, no. This whole business is somewhat confused by the Colt s/n 7886 item in TCN 145. I will comment on this shortly.
