In my country there are certain auction sites but more than anything in the capital, however there is always someone who sells wonders in front of their houses, some have passed through generations or others are auctioneers who buy and sell, but that place you visited has wonders the vasigas, the chandeliers, the telephones, without a doubt, I would visit a place like this whenever I could, of course, and have money to buy.
Saling in front of their house sounds good, as you said great pieces can be found for generations there. Believe me, even when there is no money, it is very pleasant to visit these shops just to look at them ;)
