Several threads on ATG about Trumpers seem to point to Soapworks Ltd Glasgow as the company behind the poor performing hard soaps. T&H used to have a terrible reputation also but have changed formulation within the last couple of years and it's very good now - I have the Sandalwood bowl. DR Harris is known good throughout. Actually, Trumpers Oxford Blue and Officer & Gentleman are good, but the ingredient list is different to their main brand soaps and bears a strong resemblance to T&H and Cyril R Salter.
There is a thread confirming the latest Floris formulation (with Shea Butter) to be good ("Trumpers ... are you listening?") so that bodes well

... so, yes, if you wanted other "posh" soaps, T&H are good (lathering ... and veg based), those two Trumpers mentioned above and DR Harris (although these have tallow fat in) Naturally, MWF is outstanding (but again, tallow and lanolin).
