Leon Feldhendler was an inmate of the Sobibór Camp. In a 1946 book, he is quoted as having testified that, in the sector where he was employed, the living conditions for the Jews were agreeable:
“The [Jewish] tradesmen were living very nicely, in their workshops, they had comfortable quarters.”
He claimed that the gas chambers at Sobibór used chlorine gas for the murder, but that “other gases were continuously tested.”
His claims are rejected as false by the orthodoxy, who insists that living conditions for Jews were hellish, and that an engine produced lethal exhaust gas for the murder.
