Nambu Type 90


The Nambu Type 90 was a flare gun of Japanese origin and manufactured by Nambu. It was used by the Imperial Japanese Navy and came with two or three barrels.
The Type 90 designation is from the last two digits of its year of adoption, which was 2590 on the Japanese Kōki calendar. It first came with three barrels with just less than 6,000 were manufactured. The First Model was highly polished and finished, while the Second Model was less polished to speed production. The Third Model was simplified and manufactured with two barrels for ease of production.
The barrels were made from blued steel and the body of the weapon was painted with a black lacquer. A two-position safety lever was just above the grip on the left side: up for Fire and down for Safe. The barrel was selected by a lever above the grip backstrap: left for the left barrel, right for the right barrel and center for the center barrel; on the double-barrel model the center position acted as a second safety.
The barrels had rectangular decals on them indicating which flare was loaded as standard. The three-barreled version's barrels were marked one green decal on the right-hand barrel, one white decal on the top barrel, and one red with a yellow center stripe decal on the left-hand barrel. White flares were used for illumination at twilight and night, black smoke was used for obscurement, and the colored flares were used for signalling. The shells had cardboard hulls with a brass or steel base.
The Imperial Navy's Type 90 is rarer than the Imperial Army's Type 10 for a few good reasons. First, they were made in lower numbers than the Army type. Second, they were usually issued to ships and Naval aircraft and were lost when they were destroyed or sank. Third, Soldiers and Marines who found flare guns on the battlefield often threw them away, as they were not seen as collectable as pistols, rifles, or knives.
