Help Identifying Lamp
My parents gave me these lamps upon moving down to Florida, and they have just been sitting in a room in my house since. They seemingly have no markings aside from the light bulb fitting, which says: "Leviton, Made in the USA, 250w 250v." It also says "press" near the light switch which is actually a twisting switch, which confuses me.
I believe my parents got them as a wedding gifts from a rather well-off person around 1971. I've asked my parents if they know anything about the lamps, and they haven't got a clue. Do you guys have any ideas? Any valuation?
Here are some additional pictures.
