Apologies if I'm slow on this but I couldn't find this particular page referenced on BC. If you click on Bass and then type in the model number it gives you interesting (to some maybe) info about production dates, original RRP etc.
A bit different to the serial number look up sites and useful when you get given 3 or 4 possible years of maunfacture.
