Need Stinkards? (Who doesn't, right?) I have these leftover, Mound-Builder Americans, as shown below. 15mm Eureka. Yours for $5 USD, plus postage, or will trade for a handful of Mikes Models Ancients.
Note: This mix of figures is not a complete Mound-Builder army, but maybe the figures will let you complete a Purple upgrade. My own IV/10 MBA reno is complete, so no need for these extras. PM if interested.
