indoor The MTR was Mateba's first revolver conceived and produced in the late and early s. The designer Emilio Ghisoni was driven by the desire to have revolver's bore axis as low as possible. His later guns e.g. Unica Rhino were notable for having o'clock barrel position but this first attempt is much more interesting in my opinion.
