Lantern flashlight Meyer Roeco Germany 1960

Very interesting light weigth flashlight in lantern style. Made by Meyer Roeco from Hamburg, Germany in the 1960’s. It al made of aluminum where the body has a golden glow and the other parts are shiny aluminum. Houses some kind of large battery I am not familar with so I could not find out if it works, but all contacts are there, including small bulbs. The orange top has a crack but this does not affect the working. There is a switch for the top or front light or both at the same time (and off). Handle is adjustable. Measures 16cm or 6 1/2 inch high. Check the video to see a large flashlight collection!
