Piano 15

The Fulham Palace piano, a Steinway patent grand, with the patent presumably referring to one of the patents filed by one or another Steinway listed at reference 1.

A piano which does not seem to get used very often, at least not for public events: perhaps music students get to use both it and the organ in the chapel.
