Zim was only in use for about a year , Nov 43 - Dec 44 , so not all Tiger II s would have received a coat of it as they were built till spring 45 . IRC , all but a handful of the Porsche turret version had it , and of two Heavy Tiger units in the Battle of the Bulge , one had almost all Zim Tigers and the other was about half . If you want to grab some of the Tiger II market maybe bring out a late with the 3 rows of track hanging on the turret , narrow transport tracks and other late features , the Battle of Berlin crowd will love it . I think the BA kit has the zim version covered although I think yours would be a much better kit
