Warwickshire: Hitler potty among Thomas Crapper loos up for sale

Mr Kirby said he collected the pieces gradually, as a personal project, when he was managing director.

His collection includes ornate WC pans and basins covered in floral decoration, huge old cast-iron baths, antique brass taps, polished wooden loo seats, and that potty with the Fuhrer feature.

Mr Kirby said: “These pieces are now so rare, the collection could not be assembled today.

“I no longer run a Victorian sanitaryware company, so I cannot justify keeping the collection. It is time for it to be explored and enjoyed by the public.”

Sara Morel, CEO of Salvo, a Staffordshire-based architectural salvage firm, said the company had been asked to help re-home the collection to “preserve its future”.

A video tour was uploaded to the Salvo website, showing never-seen-before footage of the entire collection.

Ms Morel said: “Touring the private museum was fun, insightful, and a privilege. As the video shows, each piece holds stories that must be saved and shared.”

The exhibits were in “fine condition”, Salvo said, with more than 1,200 items dating back to the 1830s and up to the 1960s.
