A "Type A" gun emplacement, equipped with a missile launcher, for decorative purposes or 6mm tabletop games like BattleTech.
The model in the default pic was printed in "White Detail" and painted by a medium skilled painter (me).
Due to the small size and Shapeways handling fee, this model is much cheaper as set of four
(ppu $1.75) or set of six
(ppu $1.59) turrets.
