Yeah, t'aint an original thing in there based on my uneducated guess.
Are you just trying to find out more about it, or contemplating a re-do of the bath area? Personally, I think your bath is a good candidate for all new stuff, laid out according to what suits you best - rather than trying to find original pieces.
When I get around to gutting my '63 GlobeTrotter (maybe next summer) I'll probably unload lots of my bathroom (we're redoing it as more of a yacht bathroom, with teak floor grate for the shower, etc. If our schedules overlap maybe you'll want my old sink and faucet, etc.
