It might be of greater help to know which of several models the piano
is that Sandra Moore had available.  In that period Broadwood made
Grands, Squares, Cabinet, and Cottage pianos.

By the way, a Square piano is a horizontal piano that has four sides
like a rectangle.  A Grand piano is a horizontal piano that is
essentially a triangular or wing shaped piano.  It has much greater
inherent stability than a Square piano.

A "Square Grand" piano is a figment of the imagination by the
advertising department of the piano companies, as is the "Upright
Grand."

While it is true that there were some experimentally built vertical
grands built, they were not true "Upright" pianos in the normally
accepted sense of the word.
