Couple of times, even in the official explanation of Rule 10, I've seen people state that only Iron Wind Metals is licensed to produce BattleTech miniatures, and that only IWM miniatures should be posted unless they are clearly stated to be unique kit-bashed designs.
But...I buy most of my miniatures from Ral Partha Europe. I looked into IWM when I first started thinking about assembling and painting some 'Mechs, but the P&P to the UK was always too high. So someone, I can't remember who or where, put me on to Ral Partha, who are here in the UK.
How exactly do they fit into Rule 10?
