I am looking for a secondhand Black box Kelly, and probably a Constance, what do I need to take note of? (1) Date Stamp I know K=2007, J=2006, D= 2000, A= 1997, how about U, V, Y, Z etc? I saw that some bags have these alphabets (2) Shooting Star Does a Kelly or Constance has Shooting Star on it? (3) Sale item Does a Kelly or Constance ever has sale? I think only retire or going to be retired items have a S I do not want to buy a shooting star or sale item. Anymore to take note? Please kindly advice. Thank you!
