Let's go over the facts...
The Stug IV was introduced in December of 43. A total of 30 were produced.
The OKH order was directed on December 29th of 1943.
Give or take a couple of weeks to get that order to the floor.
Finding the correct material for the order and then start putting it on tanks which by-the-way took 2 to 3 days to do.
The first layer, 5 mm thick, was allowed to dry for 24 hours. The second layer was 3 mm thick and its surface was formed into an uneven pattern with a metal comb. After drying for four hours, it was hardened with a blowtorch. (Without a blowtorch, it took eight days to harden.)
So YES, THERE IS A POSSIBILITY THAT the early batch of Stug IVs that came from the factory DIDN'T have zimmerit.
Damn, I am good!! With a little research I was able to find the "correct" answer and here it is..
Here is an early Stug IV "WITHOUT" zimmerit.
alot of you have blasted me with such wonderfull phrases, names and someone even called me "a 2 year old!"
Hey, if it makes you feel better belittling someone whom volunteered to defend this great country of ours for 22 + years, then go for it. Let me be your sounding board. If it makes you feel superior, then go for it.
All I asked for is one thing, proof. Some of you provided links and some other visual aids to steer me in the right direction to get the data I was looking for and I just posted it. To you individuals, thanks from me to you.
To those others whom blasted me, don't worry. I don't hold grudges or get even. Nor will I even blast back at you for making mistakes. Hey, we are all human and we ALL make mistakes from time to time. Hell, even I'm not perfect but I'm the type of person that will not quit untill I get all the facts, data and PROOF that I need to ensure my answer will be as correct as possible.
Have a great day and happy modeling..
