I can only tell you what we recieved, all very mixed up and in no particular order. There is my grandads application and signing up form dated 1931 giving physical description and identifying marks. There are casualty/regimental conduct sheets (loads of in my grandads - he was a bit of a rebel!),
military history sheets (general eports on when and where posted),field conduct sheets, and his release sheet dated 1945.
I think we paid £35 and recieved about 30 photocopied sheets, ours are a bit muddled because he saw active duty and was attached to different regiments in WW2.
These records meant a lot to us because we never knew our grandad and they were therefore worth paying for, however, I thougth that for £35 they might be a bit more organised than just phocopied and thrown in an envelope with no guidelines as to understanding them!
