Lovely work, Tony.
Minifigs is Caliver Books and they used to look after the range when Maveryc was in-between owners. Hysterical Games was eventually entrusted with ownership of the range and even released a few new kits and figures for the range, but sadly sales were very poor for the range and focus had to shift elsewhere. There were plans to introduce the 'Gaublish' (Goblin Gauls) and the Brutish Seelie (hippy psycho-hobbit Britons) in an expansion supplement that would have included rules for the Splata and the Noman Onager Warmachines as well as new characters for the Boche.
I personally think it would have been a good slow burner which, over time, would gather interest as the range grew and started to include more recognisable fantasy races. Elves were chalked in to be Greeks and Dwarves were going to be Welsh...
Totally mad stuff, but it was a joy to work on.
Steve Blease at Wessex Games is now looking after all of the miniatures Hysterical Games had in it's catalogue, but he has not been able to release them in earnest. I'm not sure reaching out to him right now would help particularly, but it may give an indication of which ranges would be worth starting on.
