I've made progress on my ACW project. I just finished painting the limbers and guns for my first Union artillery battery (crew and horses painted by Steve Dake). I'm using Black Powder for my ACW games, and for my armies the standard artillery battery is represented by 2 gun models when unlimbered and a single limber team with gun when limbered and on the move.
To paint the green for the guns I used GW Castellan Green, a black wash, then GW Castellan Green again, followed by Death World Forest highlights.
All of the models are from Perry Miniatures. The limber team is all metal while the unlimbered guns and crew are almost all plastic (two crew are metal). The six horse limber team looks outstanding on the tabletop. It's long though ... the base is 50mm x 250mm. I'm really happy with how these guys turned out! I hope you all like them as well.
I'm just about done basing my first Confederate infantry unit as well - so the next post will cover that (hopefully I'll have that up tomorrow).
