Personally, I'm not trying to sell a business as D. L. Bullock is.
I stand by my earlier comments and I'd like to add another.

Some years ago I met a Mr. Jose Iturbi whose comments regarding square
pianos was to the effect that they should all be collected in one place
then burned.  His opinion, as I got it, was that "there never was a
good square piano made on this Earth."

I used to service nearly a dozen of them on a regular basis and the
newest one was a 1893 instrument that looked beautiful.  I personally
believe they were great examples of advertising hype.  That square
pianos were superseded by grand pianos was not because grands were
cheaper or took up less space: the grand is a clearly superior piano,
and it is probably for that reason that much of the hype about a
"upright grand" was a popular ploy.

Later, to my way of thinking, snobbish people trying to impress others
with their obsolete square pianos started referring to them as "square
grand" pianos.  I've run into quite a number of these people over the
years.
