Hi Charles
I would be verry interested to know which German vehicles had face hardened armour and on which surfaces. I have had some thoughts on the matter myself see.

I think that PZ IV turret is face hardened, and the cats side and rear armour was face hardened, also and I believe sdkfz 231 and 232 came in face hardened armor? do you know if this is correct?
