This is the L-series Jazz bass I inherited, following the recent death of a friend in the US. The friend in question was Bruce Barthol, who played bass with Country Joe and the Fish.
The bass itself is unbelievably filthy and the scratchplate covers up a couple of sizeable routs in the body. The tuners are Grovers and the pickups are a set of Bartolinis. It weighs almost nothing and plays very well. Not a Jazz player really, but I am suitably honoured to be entrusted with Bruce's bass and it will feature in the Psych Unit. That's a band being put together to play songs by the various US psychedelic bands we have backed when they toured the UK.
I will take it over to @rumblefish for his appraisal, and decide what I will do to get it back into shape.
