Never read the Shipwrecks of Virginia book. After I sent my email to you I grabbed my handy-dandy copy of the Lusitania Controversies and looked up the dive in book II. You are correct, it documents the use of Heliox 16% as a travel gas to 320 and then a switch to a bottom mix of 12%. Then switching back to 16% at 320 on the way up and then 36% Nitrox then O2.

The story of what happen first surfaced to me from Pete and then was confirmed by Gary when I asked him. The story of Ostfrisland dive is in Shipwrecks of Virginia and the details of the mix are in his advance wreckdivng book I think.
