One set of 22 Confederates, 1 set of 20 Confederates and finally 1 set of 22 Union
Wow, nice paint bomb here! You're really tearing through the Battle in a Box and I must say they're looking very good. In regards to the regimental colours, I'm sure there is someone in the group that can help you out but in the interim you may want to check out some sites like this.
I'm delighted that the Challenge provided good motivation for you Brett. Keep an eye open when the snow flies next year for the next edition. :)
