How do I adjust the height?

Many of these lamps feature a telescopic mechanism with a thumb screw or collar on the upper shaft. Loosening this screw allows the inner column to slide up or down to the desired position. Care should be taken to support the weight of the upper section while adjusting to prevent sudden slipping or damage to internal wiring.

Were these originally for oil or electricity?

Numerous surviving examples began life as oil lamps during the Victorian era before being converted to electrical wiring in the twentieth century. The presence of burners, reservoirs or specific galleries often indicates a former oil-burning function. Later Edwardian and 1920s versions were frequently manufactured specifically for electric lighting, incorporating weighted bases from the outset.

How do I clean the brass?

Gentle dusting with a soft, dry cloth preserves the aged patina that accumulates over decades of use. Avoid harsh abrasive polishes that strip away the authentic character and softer tones built up on the metal. Applying a microcrystalline wax can protect the surface from tarnishing further without altering the historic finish.
