914866 Douglas William Clear - help

Hi, I am trying to find out about my dad, Douglas Clear: -
914866 Douglas William Clear. From “findmypast” we obtained the following:
28 July 1942 – Renlisted into Royal artillery (Field Branch) under conditions of Army Council Instruction (ACI) 1435/42.
1 September 1951 – discharged to “Z (T) Reserves”
He was in SOE and so far we have managed to find out that he was in NWE (we assume North West Europe?) from 27/10/1944 until 13/05/1945 and that he was "extracted to NSRW".
I can't find out any more than this and have emailed every military source that I can think of.

 

Only one way to go:
