A fabulous Hadrill and Horstmann counterbalance desk lamp with push button on/off switch. Dating back to the 1940’s.
Original and unrestored apart from being rewired and PAT tested.
This model is smaller than the usual H&H counterbalance lamps, making it the perfect size for a desk as it doesn’t encroach on the work area. It would also make a lovely bedside or reading lamp for the side of an armchair, again because of its neat size.
