From their announcement:
I have just listed a very rare Genestealer Magus with table consul on my eBay auctions, it has no reserve. The original was sculpted by myself (Bob Olley) when I worked for GW as a designer in the late 1980’s, at the time I was given two castings which I have had in my personal collection ever since.
It wasn’t until Jackie posted a question about the mini on Frothers Unite that I discovered it may never have been released at all. (Obligatory Frothers warning: most likely NSFW)
And here’s the eBay auction listings. BTW 10% of the auction price goes to charity
