I inherited this fender that looks like a walnut "the STRAT" from 80-83 but the headstock is wrong and says "stratocaster" but the serial number is from that same era. Anyone seen this oddity before? Chances are it is not a fake because it comes from an avid fender collector that primarily made all his purchases from one reputable guitar shop in the 1980s...soooo....what is it?? Any advice is welcomed! Help solve this mystery!
