I believe I painted this boar rider in 2009. I know it was the same year as the 25th anniversary of Warhammer, when they came out with the special edition of the rulebook. There was a bit of conversion, but I don't know what the original min was supposed to look like to say exactly how much!
At Games Day that year, they had a "Spirit of Warhammer " prize for a miniature that best fit this description. The boar rider was chosen for that, and I was given a copy of the big 25th anniversary WFB rulebook.
Here he is:
I painted this Grimgore around the same time. I had 2 different bases for him, one for WFB and another for RPG use.
