Hi their Sphinx,
Basically I can firstly confirm my old sparring partner Yoser on No 2.
No 1 - no idea - I had only joined the 1st Bn in November 1949 at Wupperpal having completed my PYTHON and had to transfer to another Lancs Bde Unit - UK was literally crawling with all of the spare bods of infantryman of all ranks who had more than six months service to go , anyone with more that that amount were given (?) the option choosing from of one of the rest of their Brigade counterparts remembering that most of the Indian Regiments had to disband their 2nd Battalions following the Partition of India and Pakistan.
2, Company Command TAC Course - TAC basically still, as far as I believe, Tactical Commanders Course - Company Platoon Movements on the Field - usually held at Warminster or School of Infantry .
3, Yoser has answered.
4. ADM Course , Singapore , 1949 - Remembering WW11 had finish, numerous problems still existed particularly in Singapore, riots over the Dutch girls and their families following their release from the Nips. in October 1948 Chin Peng and his merry men went on the Rampage from October 1948, burning Rubber plantations and murdering Planters and Policemen etc - all basically NEW to the Army at that time and presumably these Administration Courses were formulated possibly down In Nee Soon Garrison or Selarang Barracks.
Hoping that detail satisfied your queries, of not ask further and will try to oblige.
George.
