Wistar / Betsy Ross Fostoria milk glass goblet wine glasses & candy dish

Lot of hard to find Fostoria milk glass pieces in the Betsy Ross pattern? There are two of the 6" wine glasses, and a candy dish or nut bowl with nappy shape (finger ring handle).

These have some faint yellow streaks which we haven't been able to remove, looks almost as thought they were part of the glass, if that's possible? There's no chips, scratching or signs of wear to any of these pieces.
