A destroyed Magirus-Deutz van found in 1945 in Koło (Kolo), Poland, not far from the Chełmno (Kulmhof) extermination camp built by German Nazis. The same type of van was used by the Nazis for suffocation, with the exhaust fumes diverted into the sealed rear compartment <a href="https://en.wikipedia.org/wiki/Gas_van" class="extiw" title="en:Gas van">where the victims</a> were locked in. This particular van has not been modified yet, as explained by <a rel="nofollow" class="external text" href="http://ww2today.com/16th-may-1942-ss-discuss-the-use-of-mobile-gassing-vans">World War II Today (read)</a> sourced to Office of the United States Chief Counsel for Prosecution of Axis Criminality publication <i>Nazi Conspiracy and Aggression</i> – Washington, U.S Govt. Print. Office, 1946, Vol III, p. 418; nevertheless it gives a good idea about the whole process.
