He is a Leading Boy with 2 GC stripes. I was an apprentice at Locking 61 - 64. GC stripes for apprentices disappeared around late 61. I passed out in Dec. 64 and we were the first entry to have the 4 bladed JT badge as opposed to the previous single inverted chevron JT badge.
Apprentice chevrons could be a sight to behold, a Drum Major Sgt. Apprentice would have 3 chevrons on each arm to denote his rank, 3 inverted left arm Good conduct and 4 inverted right arm to denote the Drum Major.
