I'm pretty adept at locating serial numbers on machines, but this one has me stumped. My project KoD has the serial gouged out on the front of the cabinet below the coin door...I can make out the last digit only. Someone has stamped a second four-digit number into the wood near the original serial location that doesn't match the mask found on IPSND.net (it is missing the zero that typically starts off all GTB serials of the era). The final number in that second stamped number does not match the final number that I can make out from the gouged original--I'm assuming this was an operator ID number and not a serial from the factory. Also, the inspection certificate is gone from the top arch.

Does anyone know if there are any other spots where the number can be found on mid-60s games like this one? I was surprised to find serial numbers hiding under the ball lift guide and coin door trim hardware (both stamped into the wood) on a Williams Heatwave I was re-painting last summer. I was wondering if Gottlieb went to the same lengths in their serial number printing and I can finally retrieve the serial of this game.

I saw the recent thread of a Volley that had the same thing--a great way to find missing serials.

I carefully lifted all backbox cards on KoD, without removing the staples, and didn't see anything. KoD was a bit too early for this practice, I think.

I'm not worried about restoring the number. My concerns are first, curiosity and second, the addition of my number to IPSND.

Making up a number would be sacrilegious!

And yes, Pinhead is right...no stamp on the top of cabinet or on the middle arch.

The search continues...
