Hi Qajeff,
I have had a look at your photos by copying the visible URL into my browser and would have posted the photos for you as you are having some difficulty, but unfortunately your link is to a commercial website and this is against the Forum rules.
I can tell you however that your candle sticks are silver plated. The EPNS stands for Electro Plated Nickel Silver and the makers mark of JF belongs to the Brooklyn, New York company of Freidman Silver Co. They had a number of trademarks and also marketed under the trade name of Pilgrim Silverplate.
