Weston Black Amethyst Base Etched Juice & Sherbet Glasses

Lot of 4 vintage 1930's Weston Glass Co. Weston West Virginia hand blown vertical optic pattern black amethyst base flower wheel etch elegant glasses. Three juice glasses and one low sherbet glass. Juices are 4 ¼" tall with a 2 ⅜" diameter, sherbet is 3" tall with a 3 ½" diameter. Sherbet has no chips or cracks and is in excellent condition. Clear glass bowls on juice's have no chips or cracks, the amethyst bases all have chips...one having three tiny flea bites on top rim, 2nd having chips on both sides of top rim, and third having one flea bite on top rim and a chip on bottom ( see last 4 pics). I don't know if these can be sanded down, hopefully they can as they need to be saved!
