Mom's favs

I have a variety in all shapes and sizes. My mom used to collect them from various fleas/ shoppes when I was young. They appear to be potmetal with a veneered wooden middle piece. Held together with a long screw starting from the candle cup and ending at the bottom with a square nut. I have attempted to search on the internet for others to no avail. None have any marks although all have this similar style.
