I can't give you a NOC contact, but I can perhaps fill in some of the 
routing history of the situation.  

Using GRADUS (http://gradus.renesys.com), I identified the networks from 
your description (hopefully the right ones :), looked into the patterns of 
advertisement, and reconstructed the timeline (all times GMT).  

None of these blackholing more-specifics were being advertised before 
19th November 2002.  The sequencing of events suggests to me that all six 
networks "belong to" and are being managed by a single organization. 

Someone from BBN may be able to shed more light regarding the "ownership"
of the 157.237.137.0/24 subnet.

  First route. Genuity starts originating 157.237.137.0/24, and 
  continues to do so for 51 days.
                                
22 Nov 2002 (18:11)     

   Supernet starts originating 157.237.200.0/22.

02 Dec 2002 (20:03)     

   Supernet starts advertising 157.237.141.0/24.

10 Jan 2003 (01:04)     
 
   Supernet starts originating 157.237.142.0/24.

10 Jan 2003 (17:00)     

   Genuity abruptly stops originating 157.237.137.0/24, leaving 
   them providerless.

   Supernet takes over origination of 157.237.137.0/24 as well.
                                
15 Jan 2003 (13:26)     

   Supernet starts originating 157.237.143.0/24 and 157.237.144.0/24 
   together.
                                
20 Jan 2003 (23:34)     

   Your customer starts advertising the full legacy B space (157.237.0.0/16), 
   single-homed out of AS26797.  It has not been routable to this point.  
                                
22 Jan 2003 (17:00)     

   AS2116 starts advertising the /16 as well.  SuperNet is now blackholing 
   your customer by advertising the six more-specifics.  


Good luck,
