Would anyone be able to shed some light on the purpose of this 33 round box for Canadian .303 British Mk.VII ammunition? In the time I have been intrigued with this calibre I have never encountered this particular variation of box, but I recently found a couple from different sources. Regrettably, the boxes I have found had been opened by previous owners and each contained an assortment of Canadian WWII headstamps from both DAC and DI, which in my opinion fails to add additional meaningful detail as to their purpose.
In any event, attached below are three photos of the box (I added a standard 48 round box for size comparison) in the hope that someone can provide information on this box. The interior arrangement is 3 rows of 11 rounds separated by cardboard dividers.
Thanks kindly for any information you may have.
