If it's any help, I believe that the Altuos range was formerly Tabletop, and was sculpted by a chap named Tom (Obley?) who was the sculptor of the 2nd Generation Minifigs ECW/TYW range - that's the one that came after the original strip figures and before the current range (and, IMO, was the best stuff Minifigs ever produced). I have both these, and 2nd Gen Minifigs and the two are identical in size and style; in fact, I was told that Tom - who now works for Early War Miniatures - got a "cease and desist" letter from Neville Dickinson when he began designing what were, in effect, additions to the old Minifigs Renaissance range (to which he allegedly replied that that was his sculpting style and he could hardly change it just because he was now working for someone else!).
