Quoted from fns9l:LTG,
I just spent an hour going over the case inside and out, the headboard, and underneath, as well as along the edges of the playfield. I did not find a date or a date tag on any of it. I was quite thorough in my search. This conclusion leads me to believe that potentially this machine was not assigned a build date, possibly due to the fact it was the first prototype, and not a production model. If you have any information on where the build date should be located, I will gladly investigate it for you.
Post a picture of the serial number label that is on the back of the machine.
