On a visit to Warhammer World I purchased the boxed Orc Warboss on Wyvern for Warhammer: The Old World.
I never had this (originally) metal kit, this version is resin and I did like it. did think about using it for my Feral Ork army. Though I might paint it for an Orc and Goblin army for The Old World.
The model comes in a plain Forge World box.
Within the box are a number of resin pieces, some plastic wings and a large rectangular plastic base.
The original version of this model was metal. This has been re-released as a resin model. The castings were excellent.
They will need to be washed, cleaned up, stuck together and then fitted onto the base.
