ANM2 MK2 questions

i recently got an ANM2 aircraft gun and need the 100 round ammo box that goes into the type 1 box holder. anyone know where i can get one? these guns are really rare here in the states. everyone i talk to says ask around in the UK.. well i am asking and hoping..:D

here is a pic of the gun and the box holder in question.

thanks for your help.

drawings or good photos of the can would be a help also. if i cant find an original i will just make a new one..
