My understanding of this may well be faulty, but I seem to remember that Terzisky brought those maps out of the USSR when it collapsed. Somewhere around 1989-1992 is when I think they came to be known among Western researchers. By all accounts Tersizky was a really weird but knowledgeable fellow.

Thanks. Couldn't remember the source for these maps. Looking for hi-res scans of them. There are more than this one
