Interesting custom luger

Saw this over on the S&W forum...

From the ad...
I believe it to be a custom 9mm Luger build by J. Dewey around the 1960's. All the numbers on the gun match except for the barrel that was added by J. Dewey. I can find no numbers on the magazine except some proof marks and "P08".




The ad was not very descriptive of its lineage but you can make out the Dewey stamp on the right side of the rib just below the front sight.
