Hi @Kev
Edit: Luke and Oler have replied whilst I was typing, so apologies for any seeming repetition.
This particular bass is a model - high in the range - produced for the Japanese domestic market, as stated by @Oler.
Fender Japan was set up by Fender USA in March 1982 to produce these Fender-branded vintage models for the Japanese market, the first instruments appearing in May. There was soon demand from overseas for these very high-quality guitars so an export line, branded 'Squier'*, was produced with an approximate spec of the -65 range of the domestic Fenders (there were various quality levels in the domestic range, the highest being -115 on a Jazz Bass). These first Squiers were made in Apr 82 and appeared in UK shops in around June.
*Most probably know that the Squier name was taken from VC Squier, a string-making company that Fender bought (in the 60s, I think). When the very first Squiers hit the market, CBS (Fender's owners) were not happy with the standard 'Fender' spaghetti-logo and small 'Squier Series' on the headstock of a non-USA instrument and it was very quickly changed to the large 'Squier' logo.
Fender Japan continued making these domestic-market Fender JV instruments alongside the now-famous JV Squiers but, just to confuse matters, started to produce a domestic-model Squier (also with a JV prefix) in late 82 but these were not as close to the vintage spec as the export JV Squiers.
Loads of info on the 21frets site linked and there is a Squier Electrics book with good history.
