My guess is these had been converted to electric at some point and then unconverted (to needing candles) by the time I purchased them.

I’m guessing brass but could be bronze, sort of classical / neo classical with flame motif at the top.

Dimensions - 18” top to bottom

14” wide

6.5” project out from wall

I tried to get photos of any angle I could think of but if you need more of have questions let me know
