My 1967 Kapa Continental bass was owned by Ken Gorka, who was the bassist for an east coast band called The Critters in the 1960s. I bought it for a little over 100$ from the guy he sold it to in the early 1970s. It's in very good condition. I located Kenny because he was part owner of a well known Greenwich Village New York rock venue called The Bitter End. I called him on the phone there, and told him that if he wanted to have his old bass back, I would send it to him at no cost. He wasn't interested. He also told me that did not use it for any recording dates.
Kenny died in 2015:
