Roadworks lamp, old paraffin type. (Kemnay AB51)

Red body, red lens.
I haven't a clue where it came from. Whatever its history, I really doubt that any local authority or contractor will come looking for it. It's just looking for a new custodian.
It doesn't have its tank-and-wick workings but could be 'electrified' - but please, only if you can do it safely.
