Hey guys.
Well I got the bass in, there is a fair few issues. It's missing a part of the surround where its been sawed off! The string mute assembly is also missing. Probably not the sort of thing people have lying around spare! Frets look good, the sound is MASSIVE. Needs a damn good setup. Not sure what year it was made though.
Serial number is B00965.
Took a photo under the bridge and I am unsure what it actually says. However the pots look original they say 481007-A-98 and 1377811. The switch is pretty loose, it snaps back to the middle position shortly after I switch to the neck or the bridge pickup. Its an old style switch made with sandwiches of wood!
I may get my local Luthier to make a new surround or at least fill in the gaps with some ebony and a couple of issues may need sorting so I will likely not have the bass back for a while.
