This item is over 60 years old. I'm not sure how it works, but it doesn't seem to have a place to put batteries. I don't know how it operates. Two out of three lens caps are missing. Also, when the trigger is pulled, part of the metal is broken and doesn't move (photo 5, may be difficult to see). I am selling this as a junk item. How about it as a Showa retro object?
