Help identifying antique lamps

This pair of lamps was handed down to me by my great grandmother, we were always told they were very very old and valuable but thats about it. i think they said they were remington lamps and they were converted to electric but that could all be wrong.

They are rather heavy green glass with gold leaf, theres no marks or names on them but i havent taken off the felt on the bottom to check inside.

 

How old would you consider "very very old" be? And would/could you post a photograph of the entire lamp including shade? And one of the base's bottom? (I realize the base is covered in felt.)

considering the story of it being converted id assume pre 1920s maybe 1930s

 

The hardware looks more 1950s/60s; they'd need to have been totally rewired to be 20s lamps. They don't look like older lamps; the bases and paint on the glass look later than you were told.
