Heyo! I'm looking at buying a vintage J, but a couple questions are popping up re dates and value. Neck stamp is 7Dec64A, it has an L-series plate, but the number is L97xxx which technically makes it '65. But it's still an L-series. No lollipop tuners/ binding... So is this still considered pre-CBS? And which way does it sway the value? Thanks very much!
