Like I said, making a reproduction will be complicated. The control panel issue brought up is a good one, you can not put anything in there, no regular stick, trackball, spinner, etc.
The cabinet also has three sizes of wood, 3/4, 1/2, and 1/4. So many pieces, so much routering, so many angles. I know you have the equipment but it will be alot more work than you thought. I have done one myself, exact repro down to screw hole locations and every support/brace. I have all the wood done but still need to redo all the original metal parts to put it back together, just lost some steam after all the wood work and got involved in other projects.
Good luck, as I also said I think it would sell but it will have to be a Joust type cocktail.
edit: It also helped that I had one that was complete but needed to be ripped apart completely so I could exactly get every angle and groove.
