I found this thread of comments on Axis Forum on the Natzweiler gassings, and included in the thread was a post by Sergey Romanov in 2004. It is well worth a read. This section is from a piece by David Cole on the matter after his meeting and conversation with Faurisson.
I always had questions about the Struthof "gas chamber," but after
seeing it in person and meeting with Jean-Claude Pressac (who does a
very good job in his book _The Struthof Album_ published by the
Klarsfeld Foundation) and seeing many of the original documents, I can
now speak with more certainty; this gas chamber may very well have
been used homicidally. It might turn out that Struthof is the only
Nazi camp to ever have had a homicidal gas chamber...but in any event,
the matter is far from closed, as Faurisson would have us believe. The
Struthof episode also stresses the need to continually question and
revise (if necessary) the work of other revisionists, no matter how
well-respected they might be.
He does not offer any further back up or indeed proof at this point so I wonder what is the nature of his current claimed paper work proof.

However what strikes me is that this gassing of 87 people, if it happened, was a one off for a specific and macabre desire. It does seem as odd that once again we have a different process of gassing claimed. In this case it was 'salts' added to water that was then introduced into the gas chamber. If the believers are to be believed, hundreds of thousands of people had been gassed in the AR camps by diesel and or gasoline, depending on which version you read and of course by zyklon B in Auschwitz. If the wholesale killing of Jews was happening as claimed, a system with strict guidelines would have been put in place with operational protocols and written instructions as to the building and use of them. Yet none exists and they appear to have to make it up as they went, it's a type of osmosis process.
As for the recent ridiculing of David Cole here I find it wrong on every level. I may well start a different thread in support of David Cole.
