According to Frederick Fried's book, "A Pictorial History of the
Carousel",  Parker's company, C. W. Parker Amusement Enterprise, billed
itself as the world's largest manufacturer of amusement devices.  Their
line-up included "jumping horse carousels, Ferris wheels, carved wagon
fronts and monkey speedways which used live monkeys as auto drivers in
a fixed course." (Fried)

In 1911 Parker moved his factory from Abilene to Leavenworth, Kansas.
Fried's book shows a carousel that was constructed at Vinewood Park
in Topeka, but it was not built by Parker.  The Topeka machine was
constructed by the Philadelphia Toboggan Company.

By the way, if you haven't added this book to your collection, I highly
recommend it.  There is a whole chapter devoted to the music of the
carousel.  The original copyright was in 1964 by A. S. Barnes & Co.,
transferred to Fried in 1982.  It is available from Vestal Press under
the ISBN 0-911572-29-5.
