All models, stamped in back top of peghead. No "MADE IN USA" stamp below serial number! Note many serial numbers are duplicated from 1963-1969. In these cases, to figure out which is the exact year for a guitar, see the General Specs section for more details. ALSO note: It is easy to confuse 5 digit and 6 digit serial numbers from this era, and hence get the wrong year for a guitar. That is, 55555 is not the same number as 555555 (but when reading the number off the back of a Gibson peghead, these two numbers do look very similar!)
