That refin is looking shabby in places but seems reasonably priced for the UK.
Which doesn't say much about the used prices, here! That 4000 is shagged, and needs a lot of work. The refin looks crude, as does the black pickguard (with missing screw!). The missing finish up by the nut didn't just happen out of thin air! There is probably something wrong at that point, due to somebody cranking away on the truss rods. The same geezer who put the P bass knobs on there.
Money no object I would pay somebody to build me a Chris Squire or 4001S replica from this sorry thing.
