Hello there, I have a J-45 and still dont know what year it was made. I've heared 1962 or 1964. On the back upper neck is grooved 165058. Inside is stamped J-45 ADJ. BRIDGE.
It is red and yellowish. 2 metal strips of 3 round whites keys.
Can you help me out. If you need a photo just tell me and I'll send you one
Thank you
