Answer
In the United States, the only way a US Submachine Gun, Cal. 45, M3/M3A1 (the correct wording) can be legally owned is if it were registered during the 1968 amnesty registration period. If the gun is unregistered, it is worth at least 10 years in federal prison plus at least a $10,000 fine.
So, if it IS registered with the correct paperwork and transferable, it is a very very rare SMG on the public market and would easily bring $7000 or more to a collector.
