Ordnance Box or Crate? What is it.

[Quest Master]

I've had this for 25 years. I just re-found it. Is it ordnance related? What is it for? I've never seen another.

Mate,

I will have a stab at it.

It states Parts 226, Weights x 6, I presume each being 2.5kg.

The 226 may refer to an equipment table of sorts?

For what I am not sure but I have seen this type of box before and been told what for but I have forgotten, sorry.

Jock
