I think that Konstantinovsk is either Vanino or Sovetskaya Gavan, or both.ORIGINAL: SemperAugustus
EDIT:
This might seem terribly ignorant, but what is the modern name for Konstantinovsk? I can't find anything on this place... There is one in Rostov Oblast on the Don river, but that is on the other side of Russia.
There are several ports in the area most of the founded in the 1940s, Vanino (1944) and Sovetskaya Gavan (1941) seem to be the major ones... There is a town called Konstantinovsk founded in 1853, but anyone know the current name? It was still called Konstantinovsk in the end of 1910s- beginning of 1920s.
Looking in Google Earth, I see that both cities are 12 km distant, so maybe that Konstantinovsk represent both.
I bought a Coller Atlas of 1944, and another of 1935, and I'll look into them to see if I find them, when I'll have received them.
