Been waiting for the Ostwind for a while and glad to see it finally come to light!
The Pz III-J Tropen Early is a nice addition as well considering DML left that gap when they did the J Initial kit without Tropen modifications.
The 38(t) S is a bit of a surprise...but it looks to be more of a corrective issue with the fuel trailer thrown in as an added bonus to make the kit more attractive. Can't have too many 38(t) kit options though IMHO!
