I think I got one of the first ever Skaven models released for Warhammer Fantasy Battle. I never had a Skaven army, though I have taken a number of photographs of the models at various shows and at Warhammer World.
Skaven Screaming Bell from GamesDay 2010.
These are some of my original Skaven models from the 1980s.
I always liked the flamethrower model and concept.
There are rules for the Skaven in Warhammer: The Old World and most of the models for Skaven in Age of Sigmar would work, well they would need new bases.
