As there is a flap over the line of buttons running down the tunic top it would indicate that it would have been taken prior to 1942 when pleats and flaps were done away with due to economy measures. In fact you will have a short time span if this is the case as the Battle Dress was bought into the British Army from March 1939.
old rowley
I would beg to differ a little on that matey!
The 37ptn BD came in rather quickly, but not to all Regts...and the 1940ptn to which you refer (not 1942) are came in after that date...Both of these were worn well into the 1950s...
In fact there are about 4 or 5+ types of wartime BD, including the 1944ptn and American War Aid BDs and they are a bit of a minefield...
The main thing to look for is collar open with collar and tie...Deffo post 1944 then, and the collars were shortened in the 1949 version...
