According to my extensive armchair internet research, this bass answers most of the criteria for a 1980 Ibanez Roadster RS800 (it's most distinguishing feature being its unphotographical extreme weight):
However, I have not been able to find another passive model with the same finish, nor have I seen any others that appear to have a body made from 8 pieces of wood (the natural-finish active versions look much nicer). As far as I can tell, it hasn't been stripped or refinished (neck pocket, control cavity). I bought it second-hand in (I think) 1988. The nasty controls and thumbrest were added by me. The holes for a bridge cover were not.
So, is it an oddity from the Ibanez factory?
