I don't know when the change happened as it's quite tricky exploring the history, but by 08:30, 31 December 2012 it had become:The victims were gassed with carbon monoxide generated by diesel engines.
The victims were gassed with carbon monoxide generated by diesel engines. There is some historical debate over whether these engines were diesel or petrol.
and on that self-same day (somebody who obviously did not have a very active social life that New Year's Eve ) it changed at 09:08, 31 December 2012 to:
So I also checked out Erich Fuchs in Wiki and found:The victims were gassed with the fumes generated by a Soviet tank engine which had been removed from a Red Army tank captured during Operation Barbarossa. According to SS-Scharführer Erich Fuchs, it was a 200 horsepower, water cooled V-8 gasoline engine; Fuchs was responsible for installing it. It had been brought in by the SS at the time of the camp's construction and was also used to generate electricity.[
Upon arriving in Sobibor I discovered a piece of open ground close to the station on which there was a concrete building and several other permanent buildings. The Sonderkommando at Sobibor was led by Thomalla. Amongst the SS personnel there were Floss, Bauer, Stangl, Schwarz, Barbl and others. We unloaded the motor. It was a heavy, Russian petrol engine (presumably a tank or tractor engine) of at least 200 HP (carburettor engine, eight-cylinder, water-cooled). We put the engine on a concrete plinth and attached a pipe to the exhaust outlet. Then we tried out the engine. At first it did not work. I repaired the ignition and the valve and suddenly the engine started. The chemist whom I already knew from Belzec went into the gas chamber with a measuring device in order to measure the gas concentration.
After this a test gassing was carried out. I seem to remember that thirty to forty women were gassed in a gas chamber. The Jewesses had to undress in a clearing in the wood which had been roofed over, near the gas chamber. They were herded into the gas chamber by the above-mentioned SS members and Ukrainian volunteers. When the women had been shut up in the gas chamber I attended to the engine together with Bauer. The engine immediately started ticking over. We both stood next to the engine and switched it up to "release exhaust to chamber" so that the gases were channelled into the chamber. On the instigation of the chemist I revved up the engine, which meant that no extra gas had to be added later. After about ten minutes the thirty to forty women were dead. The chemist and the SS gave the signal to turn off the engine.
I packed up my tools and saw the bodies being taken away. A small wagon on rails was used to take them away from near the gas chamber to a stretch of ground some distance away. Sobibor was the only place where a wagon was used
He says nothing about the engine he installed at Treblinka or even whether that was the engine allegedly used for gassing. And apparently, at Sobibor, ten minutes was enough for certainty of a 100% death rate.Subsequently I went to Treblinka. In this extermination camp I installed a generator which supplied electric light for the barracks. The work in Treblinka took me about three to four busy months. During my stay there transports of Jews who were gassed were coming in daily.
The current article says:
A bit pointless sealing the doors of course as the back pressure would inhibit the exhaust gas from entering.The floors were covered with tin-plated sheet metal, the same material used for the roof. Solid wooden doors were insulated with swaths of rubber and bolted from the outside by heavy cross-bars.
Of course there are no primary sources: Wiki doesn't allow them as that's classed as "research", but as long as somebody said it once somewhere any old hearsay will do.
Some interesting comments from the talk page (admittedly going back to 2005 when the article was first posted)
Historical revisionism has no place on Wikipedia. As poet T. Carmi said: "What happened, really happened."
There is no debate about what Treblinka was, and how it operated, but there are a few anti-semites who try to pretend that there is. --Squiddy 11:04, 12 December 2005
