From Lost Minis Wiki
Gray Cat Castings, aka Gray Cat Studios is the casting company belonging to sculptor Richard Kerr. The company maintained its own website until around 2004 but the domain has since expired. Some Off the Wall Armies figures are still available from Steve Jackson Games' Warehouse 23 and Gray Cat Castings also did other casting work for them. There were plans for a future range called Quest of 5 Worlds mentioned in 2010 [1]
