Any chance of its being made by either of the 3 BRU's was destroyed by the 
apparent directory listing shown on that page.

Since we've had several compression methods, I am wondering if perhaps it 
an HDKIT backup, but HDKIT was configured to use a different, perhaps more 
effective compression.  Its an avenue I'd explore.  One can often deduce 
tha compression used by looking at a dump of the first 32 bytes or so of 
one of the files, which often contains an identifier string.  dEd can show 
you that information if it can read it at all.

Cheers, Gene Heskett
