Information about the game is very scarce on Google (no reference on those forums either), that piqued my interest.
So according to the interweb 1945k III from the same company(ies) is based on this game, one in-game screenshot in the auction actually shows some of the same enemies you can see in 1945k III.

I placed a snipe, but the bids went way higher than I expected, so I won't be the happy owner of this board.
Still interesting to know that it exists.
Hopefully we'll see a dump made available, eventually.
