Dating guild acoustics
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.Nonetheless, the charts below contain the best information we have on the approximate last serial numbers produced each year before 1960.There are no corresponding model names or numbers available.That said, the information compiled and presented here is the most comprehensive data set we have for dating Guild guitars.Please refer to the notes preceding each chart on how to best interpret the data.
in 1947 Gibson changed the serial number pattern and in 1954 went from white labels to orange labels.
If the instrument has original electronics some dating can be verified by pot numbers.
Once again the system was modified in 1970 to a six digit number pressed into the back of the headstock.
Unfortunately, the numbers were in no particular order. 1970 also saw the end of the orange labels on the inside of hollowbodies and acoustics.
New white and orange rectangular labels were designed for acoustics and smaller black/purple and white labels for hollow body electrics.
On another note, I saw one at the local Guitar Center, last year, that someone had tried to refinish with disasterous results.
