Thanks for the bit of information, Ed.  American Piano Co. had more
brand names than you could imagine.  I have seen some really offbeat
names, but again, it was the same piano.  To add to the confusion,
there were Armstrong pianos, Foster pianos and Foster-Armstrong pianos.
The top of the line In the Foster-Armstrong was called "Primeatone".
The name Foster-Armstrong seemed to show up in the very late
years.(after 1922)

In The 'teens, the Armstrong piano was completely different than the
others.  The Foster-Armstrong listing is correct for Foster pianos, but
not even close for the Armstrong piano in our church.  The 1926 buyers
guide also reads with much hype.  It is my understanding that just
about all piano companies built some really cheap players for music
stores, including American Piano Co.  It is very hard to get any
information through all the praise in these books.  You would believe
that ALL pianos were of high quality from reading it, and that is
certainly not the case.

The American Piano Co. upright pianos were designed from the start to
be sold under different names.  The top four lag bolts on the right side
of the plate only serve to hold a cast nameplate.  If a new line of
pianos was needed, only this part needed to be recast and installed
on the same plate they made for years.  Humm: The Tempola Piano Co.!

I have several if these hanging on the wall in my shop with different
names.  The plate is actually held in with flat screws under this,
and not the big lag bolts.  Early Marshall & Wendells did this also.
In truth, you pretty well got the same unit no matter which brand
you bought.  The early Marshall & Wendell was supposed to be built in
New Albany.  but who knows?

Researching this is fun !
