I think the early batteries were predominately made up by volunteer gunners, with a few infantry as well, so I would imagine no two batteries had the same number of gunners from one corps. Of the two or three diaries I have seen only one gave a gunners number and corps when being transferred or was injured, but as it obviously did not have a nominal roll it would be impossible to say what percentage were RGA and RFA in the whole battery.

More great information from Kevin
