Master Models' 1/350 IJN Yahagi Armament Set includes 6 15cm/50 barrels for the main guns, and 4 8cm/60 guns for the two twin AAA guns amidships. While this set is labelled for the IJN Yahagi, it is suitable for any of the four Agano-class ships (Yahagi, Agano and Noshiro have been released as 1/350 kits by Hasegawa)

The 6" guns on the Agano's are a Vickers design, and were originally mounted on the Kongo class battlecruisers, but were reusedon the Agano class in a new twin mounting. The 8cm was a newer design, that only saw service aboard the Agano class cruisers (although some were used as shore batteries).

Master's 15.2cm are very smoothly machined, and give a much improved appearance over the kit's plastic barrels.
