Hello chaps, I bought this today - it's in a very very bad state!

I was told it was a box used to store bombs by the Navy during WW2 but i'm unsure about it. There is an N carved into the box near the top but i'm sure it sure be an 'RN'?

I've tried looking around and can't find any other examples so am fully prepared for it to just be a mouldy box with no history, but if anyone knows what it is that would be amazing!

also any restoration tips?!

Thanks guys!
