I’m almost certain it was TV Silver. It is a very thin coat of paint with a lot of grain showing. It looks more silver under different light. I installed the strings the correct way and they seem ok, even with no wraps. I still need to tweak the TR, about 1/4 turn, and then dial in intonation, adjust the bridge height and pickup height, polish the frets, and clean and oil the FB. Good project for the holiday weekend.
It is a great playing Thunderbird, in very good condition other than the spot on the lower wing. It’s definitely worth getting that repaired.
I’ll add an ebony one and a white one in due course. Then the Limited Edition Custom Shop collection will be complete.
