British and Candian variations of the Bren Mag chest exist but are all essentially the same and hold 12 mags. They are a different creature from the box for the carrier.

Back on the ammo cartons, my 1943 dated Winchester .303 48 round carton is the same size and the wartime 48 round carton that Brad shows photos and size for. I also have a New Zealand 48 round carton that is 1944 production but it held inspectors proofing rounds. Would seem to be a standard size carton.

The 32 round carton I mentioned earlier is another standard type commonly encountered during the war and it holds the same capacity as the Bren magazine. Might be an arrangment that fits in the metal chest.
