Kohler’s part number for the lid is K4544, I just cannot make out the tank number, the stamp’s filled with glaze. As for condition, there are some scuffs on the facing edge of the lid, but that’s it. See photo in the gallery. Tank outlet center is 4 1/2″. Tank measures 20 1/2″ wide by 17″ tall and extends out from the wall 8″. Pair this with a Sibley or Trent bowl and you’ll have a nice set!
Comes in your choice of Chrome, Polished Nickel, or Coated Brass on the metal bits.
