Nguyen Quang Hung fought during the Vietnam war and had his arm amputated by US army doctor Sam Axelrad in 1966 after his arm caught gangrene.

Dr Axelrad kept the bones of the arm as a reminder of the good deed he had performed by treating an enemy soldier.

. . .

"When I amputated his arm [in 1966], our medics took the arm, took the flesh off it, put it back together perfectly with wires, and then they gave it to me," he said.

"When I left the country six months later, I didn't want to throw it away, I put it in my trunk and brought it home, and all these years it has been in my house," he added.

But, that said, Nguyen agrees with you:

"I can't believe that an American doctor took my infected arm, got rid of the flesh, dried it, took it home and kept it for more than 40 years," he said.
