DEmbury Lantern No 350 Little Air Giant

Conductor's lantern? Red light district? Not so fast. Lanterns like these were made as warning lights for utility vehicles like gas, electric and water. One site I saw listed this as used by the water company. It was a confusing site so I would not take that to the bank.
As this is an Embury lantern a bit of history. The company existed from 1900-1953 when it was absorbed by Dietz.
The Little Giant was first produced in 1936 and lasted until 1953. This example has a Dietz globe. Which means it could be post 1953 or it could be a replacement globe. As usual this sort of thing gets confusing now and then.
This is a kerosene lantern. Much better than the smokeless oil as kerosene actually works.
