Now, it is illegal for a manufacturer to transport, ship, or sell a firearm without a serial number stamped thereto. It is not illegal to possess or receive a firearm without a serial number, unless there is sufficient evidence to prove it was removed, obliterated or altered. Having this information, does anyone know any other way I can narrow the manufacture date down by maybe any design dimensions, parts, thread patterns, tooling, etc., or any changes made inside the receiver during these years? Pictures are attached. After his examination, he concluded the receiver has never been altered and there was never a serial number stamped anywhere on the outside of the receiver.

As far as the serial number is concerned, I consulted with a forensic metallurgist to see if he thought there was ever a serial number stamped on the receiver. The receiver and barrel do not appear to have any cosmetic work done to either, such as sanding, polishing or re-bluing.

In other words, it looks like they've been together for a long time. The finish on the barrel and the reciever match perfectly. The wear on the barrel, where it mates with the receiver, is consistent with adjoining wear on the receiver. The barrel is date coded January 1974 and is a modified choke 26" plain barrel. The forend is period correct, but the stock is from a post 1979 according to the cut pattern. The scroll work on the side of the receiver continues above the slit, which would make it built prior to 1979. From what I have found through researching various articles, photographs, books, magazines, etc., this shotgun was born between 19. The receiver appears to have never been stamped with a serial number. As you have probably concluded from my original post, I am the owner of a Remington 1100 without a serial number affixed.
