Florence, N.J., isn’t too different from other small towns in the Garden State, one marked, if anything, by a slew of very ordinary sights—chain flower shops at every major intersection, decidedly lower gas prices, and a few cozy diners. But it is also home to something else, acquired by Greg Kohfeldt when he bought Sam Carlani’s auto-repair shop here almost 20 years ago: Adolf Hitler’s toilet.

According to Kohfeldt, the toilet came off of Hitler’s biggest private yacht, the Aviso Grille, which was between 400 and 500 feet long, and at the time one of the biggest private boats in existence. “He wanted to ride it down the Thames in London and go live in Windsor Palace when he invaded,” Kohfeldt told me on a subzero morning last week as he pulled a sink—also from the ship, and now in pieces—out of a box and laid them out for me to examine each of the maker’s stamps and faucets. Another resident of Florence, Dick Glass—an expert on Hitler’s yacht—told me that the ship was armed, had a crew of 245 men, a private room for Eva Braun, and was bigger than J.P. Morgan’s ship Corsair. The Aviso Grille also played a significant role in one particular moment in history: Hitler’s Grand Admiral Karl Dönitz stood on the deck of the ship on May 1, 1945, and gave the first word of the Führer’s death and took command of Germany.
