Just adding up those civilian on foot additions

 Anachronism               34 groups (408) (64 dead)

Lodgepole Creek        13 groups (156) + 1 group (168 + 28 dead)

Alkali Wells                13 groups (156) + 1 group (168 + 28 dead)

Muleskinner Canyon    6 groups (72) + 1 group (84 + 14 dead)

Mescalarilla                  6 groups (72) + 1 group (84 + 14 dead)

Dork's Claims               2 groups (24) + 1 group (36 + 6 dead)

Bull's Butt                     2 groups (24) + 1 group (36 + 6 dead)

"Environs"                   22 groups (264) + 1 group (276 + 46 dead)

105 groups = 1,260 + 210 dead (and those six prospector mules) (1,476 pieces including babes in arms)

Might remove the 'more modern' film crew and just leave the 'old fashioned' film crew as the 'roaming' group

Over half of the above is primed and ready for painting
