- C21/1a,b,d (Goblins) - FTG9 had 2 versions each with several variants. C21/1a is the original one. There are several candidates for C21/1b and C21/1d from FTG9 - but it is likely that all of the 2-piece castings from FTG9 were available here.
- C21/1e,f,g (Red Orcs) - Fiend Factory has 3 Red Orc riders (FF27-2, FF28-2 & FF29-2), two of which probably map to 1e and 1f but FF27-2 carries a spear which is not mentioned here.
