This auction is for an original Wizard of Oz operations manual (3.1X). 

At roughly 300 pages, this wire-bound (lay flat) manual includes detailed diagrams and color photos of nearly every part of the Jersey Jack Wizard of Oz pinball machine. The manual includes detailed wiring diagrams and instructions for removing large playfield assemblies, such as Dorothy's House, which needs to be removed to replace one of the rubber rings on the machine!

A physical copy of the manual is a much better option for service than scrolling through the digital copy on a tablet or phone to trace wiring or track down part numbers.

The front cover has been signed by Jersey Jack
