surf the lamp says B@H on the cap and on the top it says patented July 1880.
Hey dump farmer,
I do believe that's Bradley & Hubbard.
" a brief historical profile of
The Bradley & Hubbard Manufacturing Co.
Certainly one of the most recognized names in lamps is Bradley and Hubbard. The company loosely began in 1852 in Meriden, Connecticut when Nathaniel and William Bradley, Orson and Chitten Hatch, and Walter Hubbard, formed Bradley, Hatch & Company. This incarnation of the company only manufactured clocks. The Hatch brothers sold their interest in the company in 1854 and it was renamed Bradley & Hubbard. Clocks remained the firm's primary product into the 1860's. In addition to their successful line of clocks, Bradley & Hubbard also produced a wide range of household items including match safes, call bells, andirons, urns, bookends, frames, desk accessories and vases.
Technological advances in drilling and refining crude oil in the late 1850's and early 1860's paved the way for the demise of whale oil as a lamp fuel. Soon after Colonel Edwin Drake struck oil in Titusville, Pennsylvania on August 27, 1859, Nathaniel Bradley saw an opportunity to capitalize on the future of this new fuel. Nathaniel's decision to produce an extensive line of kerosene burning lamps proved to be a wise business decision. Kerosene was soon to become a widely used, safe and relatively inexpensive lamp fuel."
