[dto:] to what Bish said. [Y]
The Ostwinds are murkier due to their low production numbers and the production interruptions at the end of the war…the Ostbau Sagan facility had to be picked up and moved right at the start of 1945 and didn’t resume production again until March, so there are a lot of possibilities out there when it comes to this particular vehicle. What is clear though is that the chassis you are working with on this kit is an earlier model that has a 95% chance of being fitted with zim IMHO from an accuracy standpoint. Up to you though in the final analysis on whether you want to put that much effort into an older kit or just leave it as-is. [;)]
