Horrors in the Mist
General purpose handheld oil lantern famously used by "bobbies"
A bullseye lantern provides clear illumination in a 60-foot cone and shadowy illumination in a 120-foot cone. It burns for 6 hours on a pint of oil. It has a focusing lens and shade that could cut off the light without extinguishing the lamp.
Price: 3/6 (shilling/pence)
