Antique or Vintage White Hobnail Opaline? Lamp. Fenton?

First of all what a unique piece!! I hae a lot of Fenton myself. Howeer there is so much knock off and to be honest it is hard to tell (for me) through those pictures to tell. I wish I could see the the turn peg, ehhh what do you call that... My grandmother called it a turn peg and it stuck with me Or the base of the chord or the chord itself in full detail. Since I cant be sure I am going to pass it along to my very good friend and the one tat does all my fenton appraising and trys her hardest to teach me all of the good terms, that dont stick with me. I did want to say beautiful piece and good luck.. McKenzy will answer you next from this same account, Jennifer
