Hi Graham,
I used to have a few of them when I was a kid and always thought they were cool 8)
I recently picked up this Mercion figure as part of a lot and you are more than welcome to have her if you like. She is missing her hood and staff but apart from that she is in fairly good condition. PM me your details and I will forward it on.
I also have a Warduke somewhere and a few other bits and bobs and I'll let you know whenever I find em :wink:
Here is a list of the complete toyrange as well:-

I hope you find it helpful.
