Unusual Antique Bullseye Pocket Lantern – Kerosene Police Lamp with Signalling Shutter, c. 1900–1920 – Working

Un unusual antique kerosene pocket lantern of the bullseye type, with a domed lens, most likely dating from 1900–1920. It carries no maker's marks, so manufacturer and country of origin remain unknown. Lanterns of this type were used by the police, among others — often referred to as a policeman's bullseye or dark lantern.

The clever part sits in front of the lens: a sliding shutter that "switches off" the light without extinguishing the flame, which also made it suitable for signalling. At the back are two handles and a fitting that serves as a trouser or belt clip.

The original wick holder is a bayonet type. It doesn't sit very tightly and comes loose rather easily; it works fine, but asks for a little care when closing the door.

The domed lens shows some damage. Otherwise the lantern is in good condition and in working order.
