Thanks, both of you. I would be quite happy to think that they are early 1900s which, incidentally, is what the sales tag indicated. But one cannot always believe the sales tag, so that is why I come forums like this.
Mart, I have a particularly sentimental reason to like your assessment of "first quarter of the 1900s," though I want the truth, whatever it may be. My grandparents, long since deceased, were all born in the first quarter of the 20th century. There isn't a day that goes by that I do not think of them, but I value things from the formative days of their youth and young adulthood, long before I was around. (I like older things too of course) My maternal grandfather was a steel worker in Pittsburgh during the Great Depression and WWII. His wife, my grandmother, was the kindest, most compassionate soul I have ever met, a sort of Protestant ascended master, if such a title existed. What a perfect match! One of those little hammered candlesticks sits in front of a photo of them from the late 1970s, happy and smiling and posing with some other relatives. There's a nice bit of symbolism involved in having a hand worked metal item (even if it is brass) in front of the photo of a steel worker.
Again, thanks for the input.
