It's the same reference for the black dial and the racing dial - 145.014.
This one has clear evidence of having had a case polish, probably to tart it up for sale. The brushed finish on the sides of the case has been mostly smoothed out, as has the radial finish on the front of the case. The smooth bevel edge along the side of the case looks slightly narrower than it would have come from the factory, so all together this indicates that the finish has been polished out and not just worn down through use.
The case is also much newer looking than the dial and hands, which are a bit sun bleached. So the polish looks recent. You need to see a good pic of the movement, especially as there are indications that the watch is more worn than the shiny case initially suggests. It may just be an honest watch that's had a dealer shine put on it, but you should check.
Given all that I wouldn't be paying top prices for it as it isn't pristine. Somewhere in the £1400-£1500 range might be right for this, assuming the movement is ok. I'm not totally on top of current prices, although £1500-£1750 seems to be the current range for very good examples (not many of those about though). The bracelet looks original and that counts for something too.
Hope this helps.
