Many of these drawings were commissioned by Allen Knott for his Battlestar Leonidas fan fiction. Many appear in his story under different names, especially the Raiders. Information can be found at the Galactica fanon wiki. I haven't put designs here that are exlusive to any partitcular fan fiction. Those are on their own dedicated pages.

non Canon drawings
4-bay Cylon Basestar There is some debate on whether this is canon or not. Some people insist that at least some of the Basestars seen in Razor have four hanger bays instead of five. I used to agree but now don't think this is the case but I did a drawing of it anyhow.
Singer/DeSanto Command Centurion A gold-colored version of the Singer/DeSanto Centurion.
