This beautiful lamp is marked on the bottom L&L WMC 1970. The number 9123 is also on the bottom. From the research I have done I have discovered that WMC is for White Manufacturing Company. White Manufacturing Company was in New Jersey but is now out of business. They were the makers of the metal parts of the lamp. This lamp is in excellent condition. T are 2 patterned glass inserts that are in excellent condition with no cracks or chips. T are 5 strings of glass prisms hanging in 3 different openings on the lamp. They are made of glass and all are present. T is white marble near the bottom of the lamp that is in excellent condition. The cord has a toggle switch on it to turn the lamp on and off. I plugged this in and it works great. This lamp is approximately 17" tall. Thanks for looking. If you have any questions, please ask.
