This etch is shown on page 152 of the Wheeling Decorating Book, and is called 'Sixes or Nines with Flowers'. The pattern has been adjusted to fit on the candlestick - the full pattern has a lovely band of flowers in between the two bands shown.
Etch is shown here on a Paden City #412 Crow's Foot Candlestick, but is also known on Fostoria and Imperial pieces.
