From billyrhythm.com:

Let's begin our history with what I know. The GHOST was designed by J.R. "Bob" Ramsey of Springfield Oregon, and produced in a small factory somewhere in the midwest. It featured two 3" clock style springs, one for the forward motion, the other for the return. From the rumors I've read on the net, Shelley Manne may have also been in on the design. The patent was applied for on October 27, 1947, and was granted on May 8, 1951.

The Ghost was, as far as we can tell, the first longboard bass drum pedal. This is from the classic era, before the Ghost patents were purchased by Ludwig!

This one is in good mechanical shape, but like all old pedals, would probably benefit from a nice cleaning.
