My daughter was recently given the opportunity to purchase a vintage Gibson J45 banner guitar. When she first saw it she thought it was a 1970's clone. I believe that is an original and would like some verification. She's not sure she can afford it so I'm doing some research. It is in amazing condition for it's age and sounds great. The FON (I assume) is stamped on the inside 2966. Any ideas on the age and value? Was this a Kalamazoo gal guitar? Thanks
