these 3 lamps i got after my grandmother past. i in herited these lamps and a pecan bedroom suit. i am wanting some information on these if possible. she has had these lamps as long as i knew her. even my father said these lamps was in his house when he was growing up and he was born in 1960. so i am guessing these lamps are from that era...any info or appraisal would be great thanks
