It's a Graham Noden bass.

Active and fretless by the looks of it.

I'm interested but can't find a 'currier' to pick it up.....

Passive according to the seller in the Q&A section down at the bottom. I hadn't heard of Graham Noden before just now. This does look a bit rough-hewn but if he's a master guitar tech I'd assume it plays well! I wonder if that's a DiMarzio in the neck position.
