Ash collection bins from the cremation furnaces of the Birkenau Krematorien found in the Bauhof in 1945. It is impossible to say whether they came from Krematorien II/III or IV/V and not very important if the bins were similar for the two types of furnace.

Bauleitung drawing 2221 [PMO neg. no. 20583]
Kriegsgefangenenlager Lageplan / plan of the prisoner of war camp
Scale 1:2000
Drawn by prisoner 538 and checked by SS Second Lieutenants Dejaco and Janisch on 20/3/ 43

This Bauleitung source confirms the erection in mid-March 1943 of a hut [B] running south-north in the north yard of Krematorium II, which was used, according to Henryk Tauber, as an undressing room, apparently because the access stairway to the underground undressing room [Leichenkeller 2] was not yet completed
