Like some of already know (see earlier posting of me) I have constructed a dummy Sherman tank in Balsa wood.

I don’t like the natural color of balsa (to pale) and now I was wondering which is the best way to give the wood a more aged look?
I tried drybruching a little Panzer gray on some scrap but I does not look right.
What I want to achieve is a wood that is relatively new but is a bit exposed to nature (rain, sun, ….)
Any ideas???
