Danny42C - glad you enjoyed the WW2 film clip. From 1970 until demob in 1973 I was actually a regular RAF Cpl instructor, teaching Wireless Operators, Teleprinter Operators & Telegraphists at 3 MHU, RAuxAF which was based at Mountbatten. When my posting to 3 MHU came through my then boss (at 604 FAC, 24 Brigade) thought it was a wind-up because the RAuxAF had been disbanded in the 1950s.
