Thats a real good question and from what I've read and i may be wrong so someone correct me please if so. During mid/late production they did come from the factory with Zim applied. But as the war machine was being slowed many times tanks were field modified, units were moved from Italy and the ETO to the WTO towards the end. Many of these had field mods applied as I'm hoping i am portraying. For me this has been as much of a research project as it is a kit build. Which is the fun of the whole project. I look forward to hearing what other more knowledgeable modelers may know.
