[HP]

Factory application of Zimmerit was discontinued on 9th September 1944 - the same month when the first Henschel suspension variants were completed.

EDIT: I do not know if the few last Porsche suspension variants completed in September 1944 were also finished without zimmerit. Maybe the are pictures.
