Interesting souvenired Japanese Nambu holster with names of places served written onto the front of the top flap . Those places include Nagoia-Japan, Lungayen-Japan, Nasana-Japan ,Osana-Japan to name but a few. There are Japanese symbols to the underside of the flap with what appears to ba an American soldiers name 'Buzzanca' handwritten in.
