Doesn't much resemble anything I've seen, unless at a stretch the PP4, but a PP4 is of quite similar dimensions to a single 'C' cell, not a pair of them. The No.8 is comprised of two cells end to end that are considerably smaller than the 'C' type, and has an ordinary raised cap and flat base as in single cylindrical cells, rather than being fitted with snaps.

Mercury cells and batteries were fairly widely used for a while, but weren't at all common except as button cells, and I'm not aware of any that were nearly this big.
