Is there a way to identify an original 63 jack board?? My board looks right, but only has jacking instructions. No other labels, or remnants. Is there something specific about the board material (thickness maybe), or the finger hole trim?? As always, your help is appreciated.
I'm going to sell it, but I want to make sure that it's right.......or it goes on the burn pile!!
