Less than 13,000 Indiana Jones games were produced
The Indiana Jones prototype has five obvious differences to the production model.
The famous 'Lost Plastic' was a backlit plastic depicting a sunset.
The 'Idol' from the proto is silver and slightly different from the golden production version.
The 'ropebridge' that leads to the 'Path of Adventure' is backlit.
The 'Path of Adventure' itself had stainless steel sides while in the production run red transparant was used.
The easiest way to spot a prototype is the absence of a 'superball' button as it uses the gun
trigger to activate that.
There are some pictures of the prototype here
on the excellent Mike Saunders' Indiana Jones page.
