Anyone know this bottling?

Saw this in another forum, one not quite so replete with experts and historians (Reddit’s r/rum), from a non collector who was gifted several bottles from an older family member. I’ve exhausted what resources I know to discover if this is an original 1931 bottling or a later edition meant as a nod to the 1931 edition.

Anything that could point me in the right direction would greatly appreciated. More to satisfy my own curiosity than anything, though I did promise to make any discovery known to the original poster.
