Circa 1950 “Sperzel” brand toilet seat.
Here’s one unique seat! It fits a normal round front toilet bowl. We’re not sure if it was intended for nautical applications, but it may have been. Seat is made of a white composite material, and the “U” shaped bar is powdercoated steel. This will fit on your “normal” 5 1/2″ toilet hinge bolt centers. Seat does show some scuffs, but wasn’t nearly bad enough to warrant restoration.
