Joroas,
That is actually how my Baltimore project got launched. I receive several packs of this figures as part of a larger trade!! I have half a dozen primed and in the batter's box. (Unfortunately, my painting hands have ADD and I jump from project to project like the spark on a Jacob's Ladder).
Those are of course, figures for the 6th Mass in 1861. They would be less appropriate for a Riot in July 1863 simply because of the overcoats. I don't see why they couldn't work for Baltimore election riots!
