I have a pair of electric mantle lamps made by “The Charles Parker Company”. They were my grandparents and I was told they may have received them as a wedding gift in September 1915. The metal is non-magnetic, likely brass, and is 12.5″ high with bulbs, 12″ high w/o bulbs, 7.5″ wide, and 3.5″ deep. Each “candle” has a pull chain switch. Both lights were rewired and are fully functional. I can find no specific info on them as to rarity, value, manufactured date, etc. Help please!
