I have the same question about almost identical candlesticks that belonged to my grandmother. They are solid brass (the 4 inch base screws off) and There are no maker's or any other identifiyin marks on the candlesticks. I saw a matching pair (but only half the size) in the Polin Museum in Warsaw.
My grandmother was born in Minsk in 1884. She was the only daughter. Her mother died young, and she immigrated to the States in 1908, where she married in 1910, and died in 1922.  I can think of 4 possibilities
1 - she inherited them from her mother and brought them with her to the States. (This is the one that I want to believe...)
2 - she received them as a wedding present in the States
3 - she bought them new in the States when she married
4 - she bought them used in the States.

Whatever is the real source, they were definitely produced before 1922.

They are handed down to a female descendent, and now belong to her great granddaughter - her daughter's daughter's daughter.

I'd love to learn the early history of these candlesticks.
