It had an illegal chopped off barrel and the city was gonna destroy it. I told them no that I thought my Dad wanted a .410 and he could fix it to make it legal. The deal was he had to fix it first and if it met legal specs he could buy it for $10.00. He brazed a pipe onto the end of the barrel and then put a thick walled bras pipe inside that then reamed the hole out to .410. Then, TADA, great little gun.
