In September 1912 badges for Stoker ratings were revised with badge pattern numbers four, five, six, 26 and 27(see chart). Circa 1932 the badges for Stokers were again reorganised. Among the changes was the badge designated for Stoker Petty Officers (series 6) which consists of a three blade ships propeller with star above and star below being dropped from use. This badge was reintroduced during WW2 for wear by Mechanicians who were not Engine Room Artificers. Mechanicians were motor mechanics who had entered service through the stoker branch. After gaining experience in their trade those eligible sat exams to qualify as motor mechanics. These stoker motor mechanics were different from motor mechanics who joined the navy directly into a formal motor mechanic training course and after qualification were rated as Engine Room Artificers.
In August 1943 badges for Motor Mechanics were introduced for wear by RN and WRNS ratings. The badge consists of a two blade ships propeller with a crown and star above and star below for Chief Motor Mechanic and without the crown for Motor Mechanics. These badges were originally introduced in 1923 for wear by RNVR motor mechanics and cover the series of pattern numbers 254 and 255 receptively. In June 1944 pattern 256A and 256B Motor Mechanic Branch badges were introduced. These badges were the same design as the Chief Motor Mechanic but were made in a large size for the right arm.
