Winchester Shotshell Headstamp assistance

Does anyone know the difference or the years made in the Winchester shotshell headstamp variations for the following headstamp styles.

  1. Winchester Ranger
  2. Winchester Ranger Made in U.S.A (on top)
  3. Winchester Ranger Made in U.S.A (on bottom.)
    I also have the three styles in Leader as well as Nublack but on the nublack made in USA is either on top of the word Nublack or below the word Nublack or not on the hs all.
