It was the 46th entry at Cosford. It was definitely the last of the Air Radar Mechanics, we were told that there were too many Radar mechanics
There were probably to many AIR Radar Mechs.
I know of ARM's who had to re-muster to Ground Radar to get their fitters course.
This probably was at least partially caused by the decision in 1952 to centralise all B/E training at Cosford.
Cosford didn't have any facilities to train GRM's. The Yatesbury u/t GRM's that had not started 'gears' were re-mustered to u/t ARM's.
The move to Cosford was delayed until the 15th Entry, the last that included GRM's, had passed out in 1953.
It seems as though the idea of centralisation was soon changed as some trades were moved to St. Athen and Hereford.
