My client emailed me to tell me that he'd found a "yacht company" who custom makes what he's looking for. It looks like a brass German beer stein and is about 3" tall. The piano's leg sits inside that and presumably is secured to the custom caster cup. The caster cup has a traditional base. That base is secured to the floor. Thanks!
