Completely original pickup, undisturbed coil, solder has been reflowed or re done at some point. Some cracking in the top plate as shown in the pictures but is still solid. Wide spaced pole pieces , measurement in the photos. Reads 9.16-7 on my multimeter -which could do with calibration so 9ish….- Either way this is a hot vintage P90. Probably from a post 1951 Gibson B9 but I don’t know for sure.
