Master Models' barrel set for Fujimi's 1/350 IJN Fuso (1944) has two types of barrels included; 12 of the 36cm/45 (14") 41st Year Type guns and 14 of the 15cm/50 (6") 41st Year Type. Each of these guns were built to a design which originated with the British firm Vickers Armstrong, but were constructed indigenously in Japan.

The 14" guns are machined from aluminum, while the 6" casemate guns are made from brass. Each style has an open muzzle, with good taper and barrel liners well represented.
