the Dwight 143 on the left is 3-5/8" the B 145 on the right is 4-3/8" I have not a clue as to the middle 4" tall with a smaller sized B really close to the WG. It is smooth based. There is a small glass dot on top and a 3 on the reverse(same size and position as the B). Maybe a melted or underpoured 145? UPDATE: CD: 145BF035...Thanks Icon.
