This is one rare toilet bowl. About 94% of vintage toilets bowls in existence are made to fit on 14″ rough-ins, and this one is the exception. It will fit modern 12″ rough plumbing. You will need to have a 4″ flange though, it will not sit down into a 4×3 closet flange. As for condition, it does have a chip on the rim (visible as a blackspot) and a crack that was glazed over at the factory, 100 years ago. There are also some chipping around the left side seat bolt hole. This round front bowl is intended for use as a low tank, but could be adapted to high tank applications. One only, and it’ll probably be another 10 years before we see another.
