An Unexpected WWI Project (54mm) Part 1

These are most welcome cast-offs from a friend's daughters WWI School Project. She only needed three and five came in the packet. I didn't realise that Tamiya did anything in WWI. They were beautifully sculpted and went together like a dream (see below): 

I primed them in Airfix Acrylic Grey (01) [which I am now "out of"] (see below):

I then washed them in Vallejo Wash - Sepia for dark shading (see below):

I then kind of stalled, so who knows how long until "Part II+" of this process.
