Hello Mark,
According to Bouchery, in D Day to VE Day, Vol 2.
white 156 with solid bar beneath is 107th RAC and 157 with bar is 147th RAC. As you state. But....
In Hodges / Taylor British Military Markings 1939 - 1945 it states
white 156 with solid bar beneath is 147th RAC and 157 with bar is 107th RAC.
Which is correct?
Cheers
Kevin
