These figures are from Black Tree Design and consists of two major designs. Item IA1412 is German Naked Savages which contains 4 different models from a selection of 28 different poses. Item IA1183 is Germans in Bearskins with Hand Weapons, which is distributed in a pack of 4. Both of these are available from BTD as Army Packs of 20 figures.
I purchased these figures on Ebay about 4 years ago, as a unit of 27 figures. My plan is to field at least one Warhammer Ancients Army. They have been based either as single figures on a 25mm square base or as groups of four figures on a 50mm square base. All bases are from Gale Force 9.
