Hi all, I have this old cab that I believe is a Fender Bassman or Showman. It's a sealed 1x15" with this strange speaker in it. It appears to be a P15L, but the manufacturer code (468) doesn't match anything I can find. Jensen is supposed to be 220xXX for their 6-digit speaker codes so I'm a little lost. Oxford is 465, but nothing matches 468. Jensen DID make a P15L for PA usage back in the day so that's my guess.
