54mm Knight & horse - jousting outfit - metal kit
This figure seems to represent a knight as he might have been at a jousting meet. The unicorn helmet is typical of the ornate helmets they would wear for a joust, but not a battle. The unicorn head sits within a crown, so this might represent someone of importance. Two different swords are included, both are of the pointless and edgeless variety used at jousts.
Manufacturer unknown, but inside of horse has a "D" inside an oval stamped on it.
