Vintage Williams, rose scented.
Tallow first Pens EF (Never even smelled this but I'm pretty confident it'd make my list).
Vintage Wembdon Lavender shave soap
Vintage Hershey's cocoa butter shave soap.
These all are currently available... somewhere. I have faith.
Actually available as in from the makers? Uhh:
Speick stick
MdC Foug Brain bowl
MdC Original Brain bowl
I probably wouldn't bother with a fourth. Truth be told I'd never use anything else I can buy over those three, unless I'm forgetting some. There are plenty of soaps I like (Tabac, Wilk Sword stick, TFS, etc); but I'd be pretty happy rotating those three forever, assuming we're in a world where I cant get my hands on any vintage soaps and cost is irrelevant.
MdC Fougere <- never tried it, but it has to be worth a punt if money is no object!
Vintage Yardley <- again, never tried it but there must be something there due to the hype it gets
Irisch Moos
Valobra Patchouli
AoS Sandalwood Shaving Cream - Great performance (that is actually exceeded by a few others) but the sandalwood scent has not / cannot be replicated.
TFS Bergamotto Neroli / RazoRock Don Marco (same soap) - Great performance (again exceeded by a few others) but the scent is absolutely perfect for a sunny day. Makes me want to go walking in a park and eat some ice cream.
Barrister & Mann Bay Rum - Top notch / top tier performance with a stong bay rum scent
iColoniali Mango - Top notch / top tier performance with a smoky, sweet mango scent that cannot be found anywhere else (that I know of).
