Vintage Etched Floral Art Deco Glass Candlestick Holders, Duncan & Miller?

These candlesticks are in pristine condition and feature a lovely etched floral pattern. There are no chips, cracks, etc. They have a lovely art deco winged feature at the top. They measure approximately 6 1/2 inches tall by four and three-quarter inches in diameter at the bottom. They are not marked, but look very similar to Duncan and Miller patterns that I have seen.
