Thanks all! I couldn't resist the Epic r/c robot @audrey!
@MagpieJono: it's been a long process over 15+ years to acquire most of my unreleased figures. It all started in about 2002 when I stumbled on a servitor for 50p in a second hand box in a shop in Nottingham. I didn't recognise it - after some research it turns out it was unreleased. I then started actively looking for unreleased figures on Ebay and forums - they were cheap back then as demand was low. I bought everything I could get, traded some and refined what I was after. If anything I think it's easier now - loads of GW staff sell their old figures, and Ebay listings are much better!
