Description
I cannot find an exact match to these lamps. One sticker from Underwriters Laboratories "Listed / Portable Lamp / Issue No. 77,889 / E-24914-1" says "Leviton" on the socket piece. I believe they are 1950s-1970s, possibly Hollywood Regency (?), not sure if they are Stiffel or Marbo or much else. They are heavy.
Mid Century Lamps
Based on the images both of your lamps date from the mid 1960's to early 70's and are mass produced items. Most were sold through Department stores. Values tend to be modest for them as they have been flooding the resale market since the Baby Boomer generation started downsizing and also clearing their own parent's estates. Comparable lamps often sell at Charity/Goodwill type shops for under $30.00 each.
