It was for a spray job purposes, not sure how far back they rubbed it but I don't expect you will find a Z finished to that level under 15 or 16K. Members on this forum have sold top notch stock clean restored 240's for 24K. Anyhow good luck you'll have to talk to the owner for details, I'm just putting it out there as a lead, no interest myself.
Cheers,
