Neuro,
perhaps you could shift your research skills into studying the records from this point backwards. Might want to start by contacting the Holocaust Museum in NYC to begin your inquiry as to "the records" and their "availability." In previous computers, I had saved to HDD removed and long since archived in offsite storage, the sparse but official information, especially with regards to the most significant lawsuit brought by survivors, which was announced as won "recently." I'm rather certain the successful lawyers aren't that hard to track down. I don't have those "file saves" at my fingertips anymore.
G/Luck in your search for the truth.
