Miroku Liberty Chief is a revolver produced by the Miroku Corporation in Japan. The Miroku appears to have been made for Japanese police (were armed with the Nambu Model 60 revolver), though given it's time of manufacture, it might have also been produced as a competition piece as much as a replacement. The Japanese police used revolvers during that period, but, however, the Japanese preferred to use semiautos as soon as they were able, and so Mikoru instead almost completely exported the gun to the US under 'EIG' and/or 'Liberty Chief' names. Dimension-wise it was pretty much comparable to a S&W J-frame. There also were slightly bigger "Special Police" 6-shot version. It had a Smith Chief's Special style grip, but otherwise the gun looks more like a Colt, especially with the exposed ejector rod and Colt-style cylinder latch.
