Good luck finding one, I don't think you will. I gave up on this and had to buy a zebra and a reverse zebra so I could assemble a double-cream JB for a "Jeff" replica TeleGib project some years ago. This left me with a brand-new double-black JB I resold.
I have a clean, very early production (circa 1977-78) "The JB Model" in double-cream, but I definitely wouldn't let it go cheap. If interested, feel free to PM me
I totally understand that. I'm not looking to steal one from anyone by any means. Would like a real clean one though if possible, which would of course make the price higher.
It can also happen if you followed a person posting. I've had this happen accidentally when I quoted or responded to someone once back in time and it subscribed me to their posts.
