I went out to the shop and tried fitting the Boys rifle magazine box into the ammo bins but no go! Too wide.
If you say 6 spare magazines were stored then the ammo box that holds 8 magazines is out. It is possible that a set of the Bren auxiliary pouches were used to keep 4 spare magazines and placed in the ammo bin that holds a single set separating it from the bin that holds 2 sets of Bren Auxiliary pouches full of Bren magazines. I believe there is room in one pouch for 2 Boys magazines so a set would hold 4 and the other 2 would be stored in the pouch on the front armour.
Any thoughts to this theory?
