badge, trade, American, US Navy Petty Officer 2nd class Gunner's Mate rating badge
1. A black wool irregular pentagon with square top and pointed bottom. Upon the black field is a white embroidered eagle with outstretched wings looking to its left wing, 4.6cm in height. Below the eagle are two crossed ship's guns with barrels uppermost.
2. A black wool chevron base upon which are two red chevrons, each 8.2cm x 1.0cm and 0.6cm apart.
The badges have no backing material.
Two-part ratings badges were issued as an economy measure; this allowed a petty officer, on promotion, to change the chevron element of the badge only, thus reducing wastage of the part of the badge with the specialty mark. The eagle and specialty mark were worn above any chevrons. The use of two-part ratings badges was short lived, they were only worn from 1945 to 1946.
This badge was for wear on the right arm between shoulder and elbow.
