I have an SG which I was given as a 21st birthday present in 1993. I wasn’t told anything about it’s value as it was a present. It has a number that was originally used in the mid 60s and reused in the 70s. The headstock has ‘Made in USA’ stamped on it which I believe didn’t happen before the 70s. https://www.guitardaterproject.org site says 1970, 1971or 1972.
I’d really appreciate any help with identifying it’s age and model.
Thanks in advance.
