Thanks for that info Paul. As John started off selling LJ kits which he had assembled /modified/ painted, I would guess he did the same with the Figureheads, which I think were metal kits. The only one I have is Belford but it's in resin and I assume is SRs34 which should be listed without the 'm' suffix.
Looking at the lengthy SR list, there are many I can't match to LJs so I assume he went on to making his own masters and maybe a bit of copying!
Have also found the origins of the Hog Island model which in an old DR Collectables 2006 catalogue is a John Eagan model
