Lancaster Antiques has dated this piece to the Victorian era.
We have had it converted to electricity to comply with UK regulations and the electrician fixed the gas tap into position to prevent damage to the new cable (see heart shaped key on the underside of the arm).

When fixed to a wall, the light is 38cm in height from the top of the light fitting to the very bottom of the gas key; it is approximately 34cm deep from the wall outwards, and the backplate is 15cm in diameter. There are four drilled holes on the backplate for easy fitting to the wall.

The light weighs 2.9kgs. It has been polished but not lacquered.
