Talking to SanityCheck in the original Treblinka delousing chamber thread, he was motivated to downplay the involvement of ZBL Warsaw in the construction of T-II even though there is far more evidence attesting to their planning and involvement in the construction of the camp than the firms cited elsewhere. The involvement of ZBL Warsaw in T-II undermines the entire narrative regarding the development and purpose of the camp, which was supposed to be a solo SSPF Lublin operation outside the jurisdiction of SSPF Warsaw but it clearly was not.
