This rustic old oyster light is made of brass and has come off an old ship. 

The rubber seal a begun to deteriorate and harden but it can still be opened, and could be re-wired by a licenced electrician.

The brass has aged to a deep patina with years of exposure to the air and sea. Some spots of white and red paint can also be seen. 

Measures approx: 23cm x 13cm
