Figured if the Maxim Company got the Imperial German Revolver they would make a More modern and undated version, also added the original date for the gun and just said skip it and made it to the most common round close to it which was the 10mm bullet i said screw it and made it it also able to be made into a more powerful .45 because it would mean the gun would be used in America and Germany as well as use the .44 Russian special.
