Re: Vintage Gibson dating help......?
I'm betting Country and Western for sure which was called the Southern Jumbo at various points.
They went to the Martin type square shoulders in 1963 and went to the adjustable bridge in 1964 and based on the 6 digit SN with no MIA stamp it's a 1965 or 1967.
However 2 things do confuse me a bit...
The blackguards were used on the versions with a natural or blond top while the burst versions got tort guards and the bridge on yours is upside down from what Gibson used during that time period...
Is it possible that your guard is tort and just looks black from the angle the pic was taken??
