Found this neat ammo can

[TonyE]

It says South African ammo in red on the box but the HN indicates Hirwan in Wales. Or am I missing something here?

I think the red stamping is not original to the box as you are correct, it contained ammo made at ROF Hirwaun, Wales.

It is am H51 crate which contains an H52 tin liner. Two H 51 crates fitted in an H50 steel outer.
