I appreciate the helpful comments so far. To clarify this was given to my stepdad by his uncle because “it’s a 1965 and that’s his year of birth” is what we’ve always been told. My stepdad never played it and told me never to touch it so I played it every time they left the house. By high school it became “my guitar” and I used it every day. I had no idea what I had. I’m 37 now and have never taken the guitar out of my parents house. Now that I’m 37 I have an Alvarez, Spector bass, Gibson tribute, Gibson Junior and a PRS 24. I am very excited to inherit this one day and have no intention of selling now that I’m Gibson obsessed. I simply want to track down the actual date as there is no serial or any differentiator (aside from as previously mentioned above near the neck joint which I haven’t checked). I will post pictures of the actual guitar ASAP, when I first saw the Reverb post I swore it was a different headstock but had my mom send me a pic and it’s the same. The tuners were brown abalone type and crumbled with age so they have been replaced but otherwise, all original. Looking forward to everyone’s comments once actual pictures are posted and thanks again for the help so far!
