Kätzchen APC

Gepanzerter Mannschaftstransportwagen Kätzchen (early designation) or Vollkettenaufklarer 38(t) Kätzchen
...a WW2 fully tracked APC for the Germans.

In late 1943 Heereswaffenamt WA Pruf 6 asked Auto Union to develop a light fully tracked reconnaissance vehicle capable of carrying 6-8 men in an open-topped superstructure. The vehicle was to be capable of speeds in excess of 50 km/hour, and was to be moderately armored. The prototypes were tested in the summer of 1944 and were well liked for both their layout and mobility. Problems were encountered with the gearbox and for this reason, and also because of the decision in Sept./ 1944 to limit all new constructions to 2 chassis types only. Namely the Auto-Union with Parts from the Panther or the CKD (Hetzer 38T).

It was eventually decided to just order a prototype from CKD in Prague, maker of the Hetzer 38(T) Panzerjager. The CKD prototype was actually built in 1944. It was wider than the Auto Union model and heavier, being much better armored. Its front plate was 50mm, sides 30mm and rear 20mm. It retained the general layout with the open top and the engine in the rear, but disposed with the kugelblende for the front MG, wich was instead mounted behind an armored shield as carried by the SdKfz.250 and 251 halftracks. A rear mount for another MG was also provided.

There are few models available in 15mm and 20mm, but none in 28mm yet (darn it...)
