The longitudinal and plan views on this drawing were inspired respectively by Bauleitung drawings 933 934 and 980. The chimney cross section is from Bauleitung drawing 1434 of 3/6/42, “Errichtung eines Schornsteines am Krematorium / Construction of a chimney at the Krematorium [II]”, a drawing not found after the Liberation.

This civilian drawing brings nothing new with respect to the Bauleitung drawings, except that the height of the ventilation chimney is shown for the first time.
