Sears used the name "Beckwith" on pianos and organs, Montgomery Ward
used "Windsor".

"Lakeside" is a name that goes back a ways.  The Tryber & Sweetland
Organ Co. split up in 1899 to become the E. Sweetland Co. and the
Lakeside Organ Co.  The latter became the Lakeside Piano Co.  Lakeside
was bought by Fayette S. Cable in 1904 who renamed it the Fayette S.
Cable Piano Co.  This became Cable Nelson, which was acquired by
Everett, which in turn was acquired by Yamaha.

The Lakeside name on pianos was used at least through 1949, according
to the Pierce Piano Atlas.  The Estey name survives as a house brand on
a line of electronic organs sold by Fletcher Music of Clearwater,
Florida.

Those interested in these arcane matters should refer to (or, better
yet, buy) "Gellerman's International Reed Organ Atlas."  Some of the
early history of Lyon & Healy is mentioned there, also Story & Clark
and hundreds of others.
