This is a very fine all original example of a rare Campo-Giro "tubular" prototype, a small frame handgun produced circa 1904/05. This example is easily identified as it has the full length upper slide/barrel shroud, whereas the later production models have an exposed barrel. This pistol has no factory proofmarks or serial number, but it has been hand stamped on the left side with "JC". It is a blowback operated pistol with a very unusual long hammer spur, a rear grip safety and the magazine release tucked up underneath the rear of the trigger guard and front grip strap. It has checkered walnut grip panels and is complete with an original magazine.
