Gibson ES345 pickups problem

[52 Bill]

I don't think so. Usually the date code follows the code number for the manufacturer. It might be under the shielded wires.

The Walnut finish wasn't available until 1969. The purple labels started around 1970. So I imagine early '70s. If you have the serial number, look it up on the serial number lists and see if that ids more specific.

The guitar is exactly like this one (from 1975): https://www.youtube.com/watch?v=zuYKxmkztVg

You were right about the neck pickups: on all photos the pickup is not reversed. I'll ask the owner whether he wants to reverse the pickup back to original version.

EDIT: I learned (from the owner) that the guitar is from 1977.
