Can anyone please provide the location i.e. address, of the 164 Officer Cadet Training Unit between December 1939 and April 1940? I have evidence that it was located in Colchester in July 1940, but later appears to be at North Wales (1944) and Chester (1946). I don’t want to take it for granted that it was located at Colchester during the period I am researching. Best, Steve.
