John Page [in 001019 MMDigest] said of a Wilcox & White player organ
being offered for sale by Sarah Davie:

> P.S.:  It is a "player" pump organ and is in working condition.
> It is a flat top which I have been told means it was made between
> 1860-1870.

According to Rex Lawson in his seminal article in the Pianola Journal
No. 11 (1998), "Towards a History of the Aeolian Company" -- which
I must already have quoted from three or four times on MMD -- Wilcox &
White was not founded until 1877.  It made plain reed organs, and while
a secret alliance was forged with Morgan of the Mechanical Orguinette
Co, Horace Wilcox and James White were founding directors of the
Aeolian Organ & Music Co in 1887.  If they sold a player organ before
then, it would have been made by an Aeolian constituent company such as
Edwin Votey's.

The alliance fell apart in 1889 after which W&W and Aeolian were both
in mechanical music in a big way and bitter rivals.  If this organ was
made between 1860 and 1870, it was not originally a Wilcox & White
and the player mechanism is a retrofit job.  This seems unlikely,
though.
