for sale is an all original condition gibson wiring harness, probably from an es-125. the alnico slug magnet p90 reads a very hot 9.2k ohms dc on my fluke meter. these are a little brighter and clearer than the bar magnet ones.  the pots are both dated the 46th week of 1947 are are 100% tested, working perfectly and are without any "scratchy" noises. the pickup is of the slanted mount variety, as is the cover, so my guess is this must have come stock on an es-125 or an other archtop with a non-raised fretboard. it would also work other gibson archtops of this era....
