I've got a few Gottlieb cabinets to repair, paint and stencil, etc and noticed on a World Fair that it also has these other matching numbers on it and they look to be factory. Has anyone else come across these and if so, what were their purpose?
Thanks, Doug.
The first Image is the usual factory serial number ( the cabinet had been overpainted in dark blue gloss paint before and much off the number had been removed sadly, and the second is inside the head, third inside the coin door wood frame and another of the factory serial number.
