      I have many of these yellow, red and white colors.
      I agree that sets that have wrong variants should be fixed.

      Link this to bricklink ID 3660. I went through my list of sets, following should have 'B' molds: 379-1,375-2,381-2,6075-2,6040-1,6080-1,6073-1,6061-1,671-1,6683-1,6927-1,6950-1,6931-1,6985-1,6926-1,6892-1,8849-1,6362-1,8841-1,6980-1,6371-1.

      So it's existed up to 1986 atleast.
