The MTR design was Emilio Ghisoni's first revolver design, predating his better known Mateba semi-automatic revolver. Unlike a standard revolver, this model features a lowered bore axis by moving the cylinder to directly in front of the trigger guard, this also allows for a larger, higher capacity cylinder because the size of the cylinder is not restricted by the shooter's grip, it also directs recoil forces more in line with the shooters arm. The revolver also features a unique loading method using clamshell style disk to hold the individual rounds which are then inserted into the rear of the cylinder. The revolver will not fire without the loading disk in place. This example features a adjustable high visibility post front and notch rear sights, standard maker's marks on the right side of the frame, importer and serial number marking on the left, smooth trigger, external cocking lever for single action operation, and textured walnut forend and target style grip. The revolver appears to have once been outfitted as the MTRC-8 carbine however the buttstock has been removed and is not included. Includes five extra loading disks. It is estimated only about 500 of these unique models were produced.

Excellent with 95% bright original blue finish, visible cylinder drag line, and scattered small scratches and dings. The grip and forend are also excellent with light handling marks. Mechanically excellent.
