ZUK,

There is no question that it is not original… the barrel assembly has a non-matching S/N to the receiver frame.  S/N 969449 was manufactured in June, 1942.  The barrel assembly appears to be S/N 989282, which was manufactured in August 1942.  How and/or why it is mismatched really doesn’t matter.  As a non-original U.S. marked Riot Gun, the value is approximately $750.
