I see the power supply and 5-pin cable are included as well as a case. There was a Series I bass in Portland,OR without a cord and power supply that sat for over 4 months then disappeared. (Don’t know if it sold) for $5,400. There are club members here that are trying to sell their Series I with power supply and cable for $6,500. I’ve been watching the market for Series I basses for two years now. You have a nice 44yo bass there but with all things older, buyers are going to want to see photos of the control cavities. There could be noisy controls or evidence of a leaking battery, etc.
