1953 Military Army F&L H60 MK1 Metal Ammunition Ammo Box For 30mm Cartridges field use

This has a rather elaborate locking mechanism - I have looked on Google and don't see another like it - see photos 

It's obviously had fields use and  shows signs of that but it is in good overall condition and the locking mechanism does still work 

As you unlock and lift the lid - the actual lid is hinged - see photos 

International shipping is possible but bear in mind it would likely be expensive as this item is heavy - It weighs 9 1/2 kilos as it stands without any packaging

So parcel is going to be large and heavy
