Culmak make the vegan T&H, TOBS, Floris pucks and the tallow Salter/Harris ones.
From another forum, someone asked C&S directly and they said the new 88 shaving soap will be made in the UK, so I'd wager from looking at the new ingredient lists and the ingredients lists for other Culmak made soaps be it vegan or tallow, it looks quite similar.
To echo the sentiment from the other forum, I think it's probably Culmak who will be making the new C&S 88 shaving soap.
I'm assuming they make the Captain Fawcett one's as well? The ingredients look very similar to the Salter/Harris pucks
