A set of four horses as shown, with horse collars, saddles and harness as used by the Imperial German Army.
The horses are designed for our German limbers. Or, if you prefer, for just about any 25/28mm limber you may own. They are modeled as "working horses" and so are a little larger than our light cavalry horses, which are Barbs, Akkhal Tekkes or Cossack horses.
Two horses are saddled for riding (left side of the limber; right in photos) and the other two (right or "off" side) have saddles and additional equipment.
