Just got the MicroMark nails in. Here they are on the left, compared with the ones I’ve been somewhat using so far.
Them’r small nails!
Guess which ones are real brass?
Out of impatience, I’ve used a bunch of the brass-plated steel ones, and don’t know how they’ll react over time, vs. the pure brass ones. If they do badly, I’ll chalk it up to “weathering.”
If someone, after looking at the model, presses the topic (which I can’t imagine, but for theory’s sake), I’ll say “Yeah, it’s amazing how corrosive mule pee can be, so I’ve tried to take that into account in the model.” 
Anyway, I’m almost done with the hoppers.
