To keep me pushing on, I decided to post where I've gotten to since last time. In short: not far!
Everyone now has both hands painted and the helmets as well. I originally mixed shade that matched the Isonzo braun examples i found online, but then realized I'd have to mix enough for all of my Austrians and promptly went with a shade of Vallejo brown green (or is it green brown?) that I had on hand.
I won't even attempt to make a guess as to when these will be finished. Maybe this month?
