The recent thread regarding the 1955-1956 Les Paul Junior black serial numbers prompted me to post this question.
I have owned a 1955 Junior for many years, and purchased it from the original owner in Canada.
In the photo below, you can see the faint "MADE IN THE USA" stamp above the serial number - something that Gibson did from the late 1920s thru the 1950s on guitars slated for export outside of the United States.
One thing I've often wondered - - what is the significance of the impressed letter/number code (H 499) on the top edge of the headstock?
Was this done at the factory?
Could it be an inventory number that was applied by the music store?
Have any of you ever seen an impressed letter/number code like this on other Gibson guitars?
Any information is much appreciated.
