In order to fully understand the way that the "paint distributor" worked Andy commissioned a model from Race Car engineer Bob Evans. This was made following the exact details found in the original patent drawings. An exception was made with the nozzle outlets which are interchangable to allow for further experimentation.

The inventor was a jeweler and he undoubtedly made the original prototype from various things found to hand in his workshop. The windwheel being the only component of any complexity, it must have been hand crafted.
