Please help ID old 30 round magazine
Was presented this yesterday for Father's day. Can't nail down its ID. I think I have eliminated the MPs, stens, greases, etc. Is almost identical to the British 9mm Lanchester, (see link) British 9mm Lanchester 50 Round Magazine: RARE - International Military Antiques
but that one is 50 rounds. Am almost sure mine is 30 rounds. Is 9mm for sure. Any help would be appreciated.
