Ron, Wayne wrote the above earlier in this thread, about Fremantle built carriers. I'm not clear on whether it's one or more track link patterns and/or some coreboxes for molding the sand cores for the track pin holes. Even some photos of these patterns and or coreboxes could answer some questions.
Wayne, any chance of acquiring and posting some pics of said patterns?
It seems rather crazy that they would have cast track links individually. It seems to me more likely that they would have built up a match plate of link patterns arranged in a radial fashion and then perhaps even stacked and clamped these 'flat' molds so that they were pouring what would result in a 'tree' of tracklinks once the sand was shaken off. Much like Ford SV V8 piston rings were cast. Ron do your NOS good links clearly show grinding marks where the feeder and runners were cut off - that might provide more clues to how they were arranged during molding.
If they did it this way then pattern numbering becomes more interesting...
