A 70's/80's Fender isn't a particularly desirable instrument (you have to look at those from a decade earlier to find anything half decent). As Mooh says, there are far better guitars being produced today for not much more money.
All their F series guitars were produced in Japan post 1969. Those worth a look prior to this period generally had names rather than numbers although I don't think they actually produced acoustics prior to 1963. Ray
