Greetings! I acquired this Knight Light & Soda Fountain Co. #321 Sunray lamp at a nearby antique store. It came with papers including lighting instructions, generator invoice dated November 30, 1930 from Presto, postage tag, and typed parts list. I will post these in The Lamp Reference Library. It has a Presto Sunray Lamp "K" generator. The last two photos are close-ups of the generator. It has a ribbed, dome opal shade. Sincerely, John L Kemmis
That is a marvellous lamp you have. Congratulations. I think the Sunray were the first lamp that Knight Light actually manufactured most of. Here is a 1921 ad.
