Now the issue is, that having re-assembled the bass the electrics need sorting. The output was very quiet... too quiet. So I don't want to post any photos that make it look finished until it is.
But to bring you nearly up to date, I got a meter on the pickup and couldn't get a reading. Both coils seem to be open circuit. I fetched it out of the bass to measure again - still no good. Having read a fair bit of the internet, it seems it is not uncommon on these old basses. Anyway that's for a future post
