These are original German flashlights designed to accept more normal batteries. It looks like it would probably take 2 D-Cell batteries. These are original dead stock. They even have some of the original box. The lid of the cardboard box may be missing. They may be a little dirty or dusty from storage but are in otherwise good condition. Some may be ink stamped with an RBNr. but I am 99.9% sure this marking is fake. In the late 90's a lot of real old stock items were made more "German" with stamps etc... to make them more sell-able. Still a great flashlight for camp with a nice little carrying handle. The price is for 1 flashlight. They measure about 2 3/4" X 3" X 1.5" thick.
