Lamp Set

I have two of these that were given to me by my husbands grandmother who has since passed away. I do not know how long she had them or where she got them but would love to know any information anybody might have on how old they are or who made them. There is a singular K on bottom of pictured lamp (other is put away so I would have to pull it out to look) and the plug in cord does look dated. I appreciate any help :)
