Our Assessment: The Diamondback is essentially a shorter framed Python both in the cylinder and grip frame, sharing similar aesthetic dynamics and is no less striking in appearance and mechanics than its predecessor. The model was offered in .38 Special as well as .22 Long Rifle, like this one. This revolver retains about 99% of its finish, sporting a bright, sharp bore and solid cylinder lockup with little sign of use. Those familiar with the Python line understand the accuracy these revolvers are capable of, this one should prove to be no different. This example bears German proof marks and was imported into Germany by Helmut Hoffman. Oftentimes, U.S. soldiers stationed in Germany would purchase a gun while stationed overseas and bring it back with them after their deployment, which is likely the case for this revolver. This will make for a beautiful display piece, especially with its original box, but it would also be a great shooter. Please see our photos and good luck!
