White Ensign's photo etch detail set for the Hasegawa 1/350 Nagato class battleships (Nagato and Mutsu) consists of 2 sheets of finely etched brass. Sheet A, a 1/2 sheet, has almost 100 different items, and Sheet B, a full sheet, also has slightly less than 100 items- giving the modeller around 200 different items to upgrade their battleship. Some of the parts are specific to Nagato or Mutsu, or are variant options (early, post 1937) of preexisting details. With the incredible amount of structures and details on a Japanese battleship, a set like this is really necessary to truly capture the look and feel of these towering, pagoda-like, queens of the sea.

Sheet A has most of the railings needed for the ship, as well as the ladders, inclined ladders, footropes, etc. The nameplates for both Mutsu and Nagato in Hiragana characters, and some ships specific antennas.

Sheet B, the larger of the 2 sheets in the Nagato upgrade set, has many of the larger PE structures in the set. This sheet has a multitude of platforms, more antenna and some more esoteric items, such as timber racks and blast bag access platforms for the main guns. Many of the items you expect to see are here as well, AA platfroms and gun tubs, cradles and awnings to detail the ship's boats, and many replacemnet parts for the mainmast, catapult and floatplane.

7 double-sided sheets of instructions are included, for 13 pages of instructions. These instructions include numbered shilouttes of the sheets, identifing all the parts. All the major assemblies have individual building steps; the remaining parts, mostly railings, are listed in the final text instructions.
