Hi guys, a while back I pulled 2 Gibson pickups from my 1991 Gibson Explorer 76 reissue and threw EMG's in it. I decided to clean the Gibson pickups and put them in my new Les Paul Standard 50s. I had assumed that they were 496r and 500t, however they aren't labelled. The one with the patent stamp is the bridge pickup, as the pole spread is 52mm, and the one with the Gibson USA stamp is 49.2mm. I remember them being hot pickups, they reminded me of what my buddy had in his 90's gibson les paul studio to some degree. Would this patent pickup be original and could it be a 500t?
