01-099 Armoured Giant riding on War Elephant. The story goes that Tom Meier sculpted one or more and someone else customized them to make the others, probably in the UK, the Perrys say that it wasn't them. The v1a version below is the one shown in the 1986 RAFM catalog, from the sculping is completely by Tom Meier, and is assumed to be the original.
Steve Casey over at The Citadel Collector blog shows another version, so if you have it, please let me make you an offer!
The version numbering A-F is purely for my convenience.
