Thompson Contender Pistol

I HAVE AN OLD THOMPSON CONTENDER, NOT EXACTLY LIKE THE ONE IN THE ABOVE IMAGE. I BROUGHT IT NEW IN 1970, OR MAYBE 1971.  IT HAS A 5mm BARREL AND A 30-30 BARREL WITH A 1.5 PUMA SCOPE.  I'VE NEVER HAD ANY PROBLEMS WHATEVER WITH THIS GREAT GUN AND HAVE KILLED A NUMBER OF WHITE TAILS USING THE 30-30 BARREL.  ALSO HAVE GOTTEN A FEW TURKEYS WITH THE 5mm WHEN IT WAS LEGAL.  LIKE I SAID A GREAT GUN!
