Thanks guys.
I'm not looking for a concours finish - it was delivered new in bronze green and some poor squaddie was given the task of hand painting it! (I have the original casting document which shows it was a genuine ex-army vehicle and there are a couple of miltary modifications, although it still sports civilian-spec lights.)
I'm only wanting to touch up new nuts, bolts and other bits I've applied red oxide primer to so I'm looking for a tin of matt green (not satin) to be applied by brush, thinned as required in a paint pot. An ebay shop would be ideal.
Thanks again.
