This is a cool brass Junk Light made in Great Britain! Not that the light is junk. No no, it is CALLED the "Junk Light" and they're referring to the small boat rather than the implied detritus you're imagining.
It DOES need a couple screws added to that curved bit of metal on the top as it's loose at the moment, but a couple tidy screws and you'll be off to the races!
Light it up, friend.
Measures 37cm x 15.4cm x 15.4cm
