This is an original WWII M3 37mm anti-tank gun. This is not one of those reproductions built from a kit......it is an original WWII piece. The only parts that are reproductions are the breech ring and sight mount. Because this cannon has a reproduction breech ring, it can be sold without any ATF destructive device paperwork. If you ever wanted to make this a live fire cannon, all you would do is submit a Form 1 to the ATF and once it was approved, you could install a live breech ring. The barrel is in very good condition and would be perfect for live fire. If you have any questions, please feel free to email me at [email protected]. This cannon is located in Paris,TN and can be picked up here. It can also be shipped via common carrier. The cannon weighs around 1000 pounds and can easily be moved around by one person. Don't pass up a rare opportunity to own an original piece of US WWII artillery!!
