G'day Thread, this is Dave from Down under in Australia Oz.I have been trying in vain to find the age of my beloved F-55-12.the serial no. is 322 105 there is no date stamped anywhere and by the serial no. well that gives no clue to the manufacture date unlike,'Guest Johntrom" stating his serial no. is 7401.I puchased this guitar in 1979 second hand.the guitar had some years on it already but how many I don't know.I am not interested in it's worth I never sell my guitars, they are my family. My wife left me but my guitars are still with me.well good luck in your search.If anyone out there has an idea of the age of my Fender F-55-12 please post some info .cheers! David
