Ammo Case as Loadbox

[LostDOG]

Somewhere on this forum I saw a pic of a guy using an ammo case as a load box on the back of the bike. As a starting point I like the idea of this until I have decided what would suit me best.

Can anyone tell me where I could acquire an ammo case - the plastic military variety?
