Thank you for the added information Warmtoast - Wiki does give an explanation of 136 Force.
Danny, I should have made clear that John attended 177Squadron re-unions as a guest, the result of bring their C.O, George Nottage , out of the jungle after his crash landing.
I have spoken to John's son. The log book is missing as is a very valuable collection of stamps. He has searched his house and has John's medals plus the escape map and the Japanese flag that John brought home.
One page of John's log book that I did photograph gives a clear picture of his movement through Burma with General Messervey and 4 Corps.
