Zimmerit was introduced Sept. '43 & discontinued September '44 (If I remember right).
Tiger1 was produced until August '44.
So theoretically all late production ones
should be zimmeritted.
Though as this is the crazy world of German tanks this doesn't necesarily mean that
all were.
The Vimoutiers Tiger is a 1944 product but doesn't
appear to have the paste anywhere other than on the glacis step... hard to tell from grainy black and white pictures though:
The Vimoutiers Tiger.
I sympathise with the modellers fear of Zimmerit... I've avoided it succesfully myself so far
.
Cheers,
Adam.
