@ Feuer frei: great pictures of the Stug you found there!
The Stug in Poland seems to be a different one and a type IV, here are some pics of the recovery:

The condition is far worse, as it wasn't sealed airtight like the one conserved in the bog.
According to this forum:
http://militaria-archiv.com/archive/...hp/t-8290.html (german) our STug III was found near Velikiye Luki - this is much closer to Pskov from the above sources. This would also put the possible timeframe again to spring '43. 1945 it was already game over in this area.
Here is a picture which allegedly shows our very same "bog Stug" in operation, found on this site:
