Les Paul Classic: This model features an ink stamped serial number with no “MADE IN USA” (just as we used on the original 1952-1960 Les Pauls).

There should be a space after the 1st digit with the 4 and 5 digit serial numbers, and no space with the 6 digit numbers.
From 1975-1976 a transfer was used for the serial numbers.
The transfer contained an eight digit serial number as well as "MADE IN USA". There also were some bolt on models with a date ink stamped on the heel.
