The turret is definitely too high and the shape is wrong, too. But nevertheless an impressing scratch-built work.

There is a photo of tanks of 11th tank regiment standing about naval base Kataoka. On them yellow strips are very well visible.
Here the Japanese text, about truce envoys.Most importantly, I want to find out about activity of Japanese negotiation team.
On the Soviet memoirs, on August, 18th there was an attempt of the Japanese party to send officers for an armistice, but when to them the soldier has gone (it seems, the frontier guard) from the Japanese positions on it have started to shoot. Reciprocal fire has been opened.According to some Japanese veteran's interview, the negotiators with white flag were sent to meet with the Soviet head detachment (lead by Major Shutov) during the first hour of the assault, but they were shot at by the Russians, and had to retreat.
Possibly, it is a question about КТЩ КТ-152.Also, in some descriptions of the Shimushu operation, I found a mentioning of what appeared to be a suicidal dive of damaged Japanese torpedo bomber (presumably, B5N "Kate") into Soviet mine sweeper, that sunk after impact.
I have memoirs of the Japanese, were taken prisoner and have been taken out to Kamchatka.I realize, that entire Japanese garrison of Shimushu was taken POW, however, were there any official reports from those, who survived GULAG?
