They work well in either role, IMO. I know in the past before we had so many great choices, I painted ESCI Russians to stand in for Prussians. At this scale (IMO), the differences are so minor as to be painted over or just ignored until the real deal came out.
Flambeau quickly solved the riddle.
Therefore 100 points go to him..
When I unpacked the set 219 a few months ago, I already had the idea that you could also make some nice Prussians out of it.
But when I had the figures back on the table a few weeks ago, I doubted whether I should work on the beautiful figures with a scalpel.
But I also had quite an aversion to paint Russian soldiers at the time.
So the die was cast... And the scalpel did its job.
