Benno's site has a small ilustration of the Italeri ACW farmhouse and barn. It looks very much the part with a veranda for ol' granpappy and his rockin chair and the barn would be great for Amish wargame figures (if there were any). What's more for greater authenticity these gizmos will conflagrate like the Fredericksburg originals. Seriously though, some civilians* of this period to flee or inhabit these buildings could be ably provided by another well known figure manufacturer.
