My Uncle was in the USN and Picked this carbine up off the Docks at Tokyo Bay. They were running jeeps into the bay and pushing crates of weapons over into the bay. One of the crates was broke open and out popped this nice. National Postal Meter with a Underwood barrel. The interesting thing is that it has a flaming Ordinance bomb on the barrel. I have several other carbines and none of the others have this. Any pros out there know? Worth?
