I am looking at my father's WW2 military record.
He was in the above and spent some time based in Suffolk at the HQ SADE (Specialised Armour Development Establishment), possible 1942-45
Most abbreviations I have resolved but any enlightenment for these below would be of great help
R.A.C
W.T.P.P
"Posted to authority RAC Reco Administration A41/9283" in 1945
"YL7 list, authority EC Form R2 F/2" in 1946
"Class 'Z' (T)", Royal Army Reserves in 1946
1954 - Discharged having attained the age of 45, no further liability for recall.
