Alastair,I took a couple of pics of the few rounds I could get too,I have more but they are buried under loads of crap !
Pictured is a C263 ammo box and the 6 pdr tool box that is listed in the spares book,Rounds from the left are APDS,DRILL,HE,AP and another APDS.
The second pic showes a very unusual B166 box stenciled to take 6 pdr Blanks,dated '44.
If I unearth anymore I will take some snaps.
