This is the Wilkinson Platinum Series Bass Pickup, with  Single/Double Coil option.  You can have the stingray sounding coil at the front or the jazz sounding coil at the rear or a mixture of both.  A few marks at one end where I was clumsy with the screwdriver but are only really noticeable close-up. It's the same pickup as in this bass: https://www.jhs.co.uk/products/guitars-folk-instruments/bass-guitars/vintage-basses/vintage-reissued-v80-bass-golden-amber Our very own @Dood di
