Thanks both for the information clarifying 23rd Field's markings.
Great info Barry.
Photo is ideal.
John,
I have had a look at the BP photo again and it does not look as though there is a bar below. So I don't know?
"British Military Markings 1939-1945" does not give an AoS for 86th Field. But the RA site (ra39-45) has a marked Sexton with 1147 with bar below as an example.
Can either confirm names on the photos posted?
Thanks again both for your help.
Cheers
Kevin
