Poles admitted they made the exhibits for the Auschwitz gas chambers in 1948. The crematoria guidelines from the manufacturer said they would need 60 kilograms of coke and coal to operate. That means 60,000 metric tons of coke and coal would be needed at Auschwitz which were not visible in aerial photos taken by the OSS. The Germans did make petrol from Silesian coal at Auschwitz.
