Some information found on the Internet mention that Chinese fisherman could still see the 41cm gun placed on the Soviet territory across the river until 1960s, then it disappeared.
Hello, in 2009-2010 I worked in Russian military archive in Podolsk (CAMO) near Moscow, there are many documents about August war 1945. In 2009-2011 I am twice went to the Hutou and saw fortification of Hutou fortress.
The plan of 410-mm howitzers casemate is a part of Soviet album of Japanese fortification in Manchuria, 1945. One exemplar of this album are located in CAMO, other exemplar in Central museum of Artillery (St. Petersburg). I think one of my copy achieved to this forum.
CAMO documents says, in 1946 Red army moved Japanese 410-mm and 305-mm howitzers from Hutou to the nearest soviet city Iman and sent them by rail to the West. With them were sent to repair two Russian 305-mm howitzers model 1915. Two other Russian 305-mm howitzers left standing in their positions near city Iman. One of them were standing close to the bank of Iman river, at a distance of 2-3 kilometers from Hutou. I think Chinese fishman until 1960s could saw this gun. But your message very interesting, I don’t know place of Ussuri river, where a fisherman could saw the gun.
