About 20 years ago my father bought this old military flashlight. We used it for a few years until the battery ran out.
The torch worked with non-rechargeable batteries and the light emitted wasn't much... It has been unused for many years but I think it still works.
To give it a new life, it's time to update it, with LEDs and rechargeable lithium batteries.
