A new build probably don't have that it would just be body color overspray usually.

The only thing that would scare me is people do reproduce the body and necks these days and you can purchase a neck plate from a parted out Kramer so if you go look at it I would say open the control cavity up an see if it has the thick shielded black paint on the inside of the control and tremelo cavity regardless of body color. The EVH paint is definitely not factory but if it's a pro job that's a plus if you like it.

The old ones are just stamped Kramer then the serial number below. As far as I know there were no serial numbers on the the backs of Kramer necks, unless the ESP one came with one, the neck plate would be a cast one that say Kramer neptune NJ instead of the chrome steel plate. I think the serial number should be a late C serial number but more than likely is a D or E serial number.

You might want to go look at it if it is local and see if it is a quality guitar, the all Maple neck seem to be rare even if it is ESP. I think that was 83 into 84 or 84 into 85. Most of the Barettas came with rosewood fingerboard neck like the holy grail white baretta in the Kramer magazine ad with EVH holding it. The body should be either Poplar, Maple or possibly Alder if it's an ESP. If it is indeed a an authentic 85 Baretta it might be worth $800 or so.
