This fretless DA bass came on the market in February 2016 with an asking price of $2,400. Seems to be mostly original, with the exception of the newer (Kent Armstrong?) pickup and Kramer HSC.
"This is a late '60's vintage bass. Some player wear on the back of the neck and micro-scuffs on the body but overall in good cosmetic and playing condition. HSC included. SN# D2234A."
