This seems to answer my question as to whether or not the seperated pairs might be stereo lantern slides, presumably these are negatives as well?

This is the sort of thing originaly done when lantern slides were produced from negatives before there was transparency film, but then there was less magnification involved so less problem with grain. Perhaps black and white transparency film could be used and the first negative stage of development omitted going straight on to the second dye developer to produce a dye based negative image. A very fine grain negative film could be tried but this would tend to reduce contrast.
