The photo is not a firearm, and exclusive camera. In 1954, the Japanese company Mamiya released on request of police, only 250 of these cameras. It is difficult to say how many of them left at the moment, but one of them for sale on eBay with a starting price of $ 25, 000. The camera is preserved in good condition (except for a pair of minor scratches on the leather handle), and most importantly it up still working.
In 1993, the same camera was sold for $ 16, 500 in the auction house Christie`s.
