Thanks all I ended up buying the Squier, but you all knew that was coming anyway, right?
Turned out to be a really decent Bass, chap had bought it over 15 years ago, with the best intentions of learning to play but never really bothered.
No (and I mean ZERO) fret wear, truss rod works fine. Pots a bit scratchy (to be expected), Jack socket needed tightening. Strings were OK, still pretty bright. You can't see from the Gumtree pictures I showed above, but it's a Metallic Black colour.
Gave it a once over on the weekend, set it up to my taste and I'm really quite pleased! Perfect Backup Bass.
