Dion Ruppert from Germany sent me these photos of a very special variation of the TL-122 flashlight that I had never seen before. At first sight, it looks like a TL-122-B or C, but it is not made of plastic. The whole body is made from a zinc-aluminum alloy (zamac) that looks like it was green anodized.
There are no markings anywhere. It has a spare bulb in the battery cover. It also looks like the actual switch has had the rivets removed and replaced with screws.
