For clarification, here's a close-up of that 1973 4001 FG:
A previous owner had removed the original bridge pickup, filled the rout, and added a different pickup mounted at an angle.
I had borrowed a horseshoe surround from Ilan and found that it would have covered the modified area, so I had planned on restoring it with a RI Horseshoe ... but then it was one of the ones that got stolen.
