Updated 04 March 2014

A Japanese version of the Elswick 6" (15.2 cm) gun.  Still in use during World War II as coastal artillery.  Interesting in that the Protected Cruisers of the Chikuma class had a uniform armament of six of these guns at a time when mixed batteries was the normal fashion.

Redesignated as 41st Year Type on 25 December 1908.  Redesignated in centimeters on 5 October 1917.
