Model by Thomas Anderson.
For the Ostwind only factory fresh vehicles were used, except for the prototype. A six-sided open-topped turret was mounted, in place of the normal turret, on converted Pz Kpfw IV chassis. The turret could be traversed 360° to bring fast, effective fire on air or ground targets. Issued to the Flugabwehrzug (AA platoons) of Panzer regiments in Panzer divisions. Even Count von Seherr-Thoss, the designer of the Ostwind, doesn't know exactly how many Ostwind were produced (although it probably was in the range of about 40 vehicles). We do know that some test vehicles saw troop trials in September 1944, but by the end of that year the production facilities were being moved constantly to keep them one step ahead of the Allied advance. Ostwind production Jentz (Panzer Tracts 12) refers to a 1st April 1945 report that six vehicles (completed March 1945), intended for Fla-Pz.Kp.z.b.V., were available for issue at Bielefld but does not say whether they were actually issued, let alone saw combat. Terlisten (Nuts & Bolts 13) gives the figure as seven but is also unclear on which unit received them. He does mention the production facility moving to Teplitz-Schoenau in January 1945 and speculates that if they did see action, it is likely that they did so on the Ostfront in this area. Seven Ostwind were produced in March 1945. s. Pz abt. 507 had some Ostwinds in 1945.
The only information I know so far is that sPzAbt. 507 received a few or at least one of them at the end of the war. But at that time they haven't been a sPzAbt. anymore, but were reorganized to a PzJgAbt, if I remember correctly. There is one photo taken at Nove Benatky, which probably shows one of them. Possibly at that time they might have been part of KG Milowice. The Ostwind destroyed in Nove Beatky belonged to the Kgr. Milowitz indeed. This Kgr. was made up from the garrison of the Military area Milovice and trainees and instructors of a Panzerjaegerchule which was located there. Personal of sPzAbt 507 (redesignated into PzAbt 507) was among them too.
