Unreleased unseen Heroquest (?) prototype figures (Bryan Ansell's collection)

This is potentially something a bit special. I say "potentially" because there's a bit of a mystery surrounding the origin of these figures. They were all found in a zip-lock bag in Bryan Ansell's collection with "HEROQUEST" written on the bag in marker pen. Although I can say for sure these are unreleased sculpts, I cannot be certain on their link with Heroquest. First the figures, then the reasons for why they are a mystery:

Unreleased Rogue Trader adventurer (Bryan Ansell's collection)

Today's offering from the Ansell horde is yet another unreleased Rogue Trader Adventurer:

This figure is labelled "Feral Shaman" on the tab and was produced in 1987. I don't know who sculpted it but at a guess I would say Trish Carden or Aly Morrison. Could be wrong though. No idea who painted it but it was part of the collection of Bryan's painted Rogue Trader Adventurers that can be found in this advert from White Dwarf 99:

I have no idea what he's carrying under his arm - any suggestions? Also, does anyone recall reading about feral shamans in the old Rogue Trader rulebooks or White Dwarfs, or do you think he's just a "generic character"?

Unreleased playtest/prototype Titan (Bryan Ansell's collection)

Work and family commitments have resulted in a lull in my blog posts recently, but now I'm back and my unreleased cup overfloweth. I've got plenty of fine figures to show you, both from Bryan Ansell's collection and also ones I've accumulated for my own personal collection over the last few months. So, on with the show.

***PLEASE NOTE*** this blog post has been updated since the start of the day. I initially though I was blogging about an unreleased Rogue Trader era robot but it appears it's an unreleased playtest/prototype Titan.

Today's offering was found in Bryan's collection and is an imposing Citadel Miniatures unreleased playtest/prototype Titan sculpted by Bob Naismith (thanks for confirming that Bob!):
