I saw a 1922 model 12 2 pin rib trap gun wendsday that has the us and flaming bomb on reciever the serial numbers match on both halves of the gun did they ever use them as trainer gun to teach lead to tail gunners in the wars gun has 30 in full barrel never seen another like it before  

The WW I guns were not ordnance marked, and they were Model 1912s.  When the U.S. military purchased the next batch of guns for WW II, the guns were rolled marked on the receiver underneath the ejection port.  You did not mention where on the receiver frame the gun in question is marked.

That’s where it is marked under the ejection port right side of reciever i will get pictures next time I am there

  

The Model 12 was not marked in that location until the WW II production.  A 1922 production gun is way too early for that marking.  What is the serial number on the gun in question?

It was in the 270,000 -280,000 range can’t find what I wrote down going off my memory

That would put it in the September 1920 – March 1921 time period, and the ordnance markings on the receiver frame are extremely likely to be faked.
