Lantern - Metal - Rifle lamp

I am selling a World War I rifle candle lamp. Thanks to a special pin-mounted support, it was inserted into the rifle barrel and carried on the shoulder to light the way during night transfers. Inside, a wax candle was placed. The connector to the rifle barrel was wrapped with a thin hemp thread to prevent metal-to-metal rubbing. The three walls are made of mica glass, suitable to prevent cracks from thermal shocks.
