I don't think it's too hard to work out the OP's typo as his question was in regards to magazine boxes NOT box magazines but an interesting question.
I always ment to have a look at a stash of Aussie L2A1 magazine boxes to see if they were ex UKicon 303 conversions or UK L4 boxes or Aussie made.....anyone got one that they can look at ?
