I have some of those figures that I bought from Vince at Historicon years ago...not the Female Sepoys though sorry. Not the best figures in the world, but I wish someone would put them out again...someone somewhere must have all the molds right?
Not to be a downer but from experience in miniatures since the very early 1970s that would be the best possibility. All the below I have experienced directly or indirectly.
Someone may have the molds and/or rights to reproduce (I have encountered both of those separately causing great frustration since the molds might as well have been since neither set of figures was available because you really need both to legally reproduce the figures.)
Usually people buy them with the intent of reproducing them. That is the best outcome (and hopefully the most frequent.)
Or they may have been destroyed (intentionally or by heirs who had no interest in the figures.)
Can the mold materials be recycled? I assume some can.
Or the molds might have been lost. One person bought an old line of figures with many molds (not terribly organized and not really documented in writing.) They are unable to locate several figures in the series because the molds don't seem to be in the set sold or at least the molds have not been found - the individual wrote me that he is still discovering what some of the molds actually produce as time and $$ allow.
At least part of the series is available currently.
Or the molds might have been bought by someone who decides he or she doesn't want to reproduce them currently.
Now that one I don't really understand but I am sure he or she has reasons that satisfy him or her.
