Really nice looking higher end C.E.C tonearm from early 1970's.
With wiring in tact...no headshell.
Was going to use this on a project but lost interest.
The BA series tonearm were used by Marantz and Yanaha manufacturers for some turntables and supplied by C.E.C. from C.E.C.'s manufacturing plants in Japan. This is also why most C.E.C. supplied tonearm had no visible C.E.C. maker stamps and are identifiable by their appearance.
.. maybe your starting a custom turntable project?
