need suggestion on a group of lamps

from a local estate auction. All vintage, just not sure if there is any collectable value

 

none are of my own particular taste and style

 

Why do they never have shades ??? Shades are so darn expensive now I quit buying old lamps !

 

nothing there speaks to me........

 

I don't know why anyone in this day would want an obsolete lamp

Brass is $1.50/lb. Check with good magnet.

 

I do not believe this is a lamp.
I'm thinking samovar missing something. I could of course be wrong, but why does a lamp have a spigot? Also missing something.

 

This looks like Czech glass, but someone has painted the brass, or it is corroded.

 

Looking again, this might be a home made something with Czech glass.
Something isn't quite right.

Someone might have made an electric lamp from the base of something else.

 

second and third from right could go under industrial, which sells good.
the public library lamp with the yellow shade could bring a bit of money as well when seen by the right people.
don't see enough details of the others.
