Dog Ear P-90 pickup I.D. Marks?

[bluezguy]

I just bought a used (in excellent condition) Gibson P-90 Dog Ear pickup.

 

I am used to seeing some kind of identification marks or text or graphic on the base plate underside of all Gibson pickups.

This baseplate has nothing on it and, it is a typical two wire vintage style wire.

DCR at 74 degrees reads 8.20k.

Seller is a vendor and says he just pulled it out of a Les Paul Junior.

 

Thanks!
