Just to bring the thread back after my little ramble there... this Mark King Deluxe is #14589, the next number after my Custom fretless #14588. Separated at birth. I keep the picture in case we ever meet up somewhere.

 Just see Ng this threas, it is right until my alley.  Very very cool.  Don't ever sell!!! (Or was boy sell as a pair!😋)

Either I was heavily medicated when I wrote that response... Or Siri misinterpreted!  Sorry about that!
