Yeah it is pretty easy to do the unit badge, it was just flat geometric shapes over top of the uniform brown color. I tend to over think and over do things, so I'm trying to test paint more and I'll be doing another one which I hope to streamline a bit more...
This WW1 project is lower priority than the modular trench table and even some other stuff... I'm unemployed right now, so I'm trying to paint more, but it is damn hot in Vancouver for a Northern Barbarian like myself. I could put a spot of brass for the C22 unit badge perhaps, but I'd just have to explain it, the colored markings are why I'm mid to late 1916 as they were introduced mid-war.
Cheers,
