Brown paint used for 1960's ammo chest?...

[starshell]

Hi chaps,

Does anyone here know where I can find the exact colour Brown used on British ammo crates/chests/tins?
I have a 1961 metal box which had been shot blasted and I would like to repaint it to original Brown colour. It has traces inside, which is intact, so would like to match it all up.
Also, any idea where can I find this paint in a spray can??
Lastly, does this paint have a NATO, BS or RAL no.?

Many thanks in advance,
D

BS 381 Service Brown 499. Gloss level makes a huge difference to shade in this colour.
