Half will be given blue carriages and half red. They will serve for my Stagonian Wars forces as well as for other periods (with different artillerymen, of course).
Of course this means that besides painting the guns, I will have to paint up a bunch of oxen and horses as well . . . and, of course, artillerymen for a variety of periods.
"Why am I doing so many?". . . well, because I had them I suppose . . . and having them, I might as well paint them, right?
