I failed to finish anything in time for World War One, but I have two ideas in mind: a Russian Civil War tank and a Whippet in Ireland, sent there for the one-year anniversary of the end of the Great War (ostensibly).
But the paint I mentioned is UK Bronze Green. Meant for World War Two presumably, but if I read correctly, British started out with green but had to move to brown temporarily due to lack of appropriate pigments, then moved near the end back to a green similar to US olive drab. Anybody know more about this?
