Trumpeter 05528 1/35 Ger. Neubaufahrzeug(Rheinmetall)  [TP05528]

Development of the Neubaufahrzeug (German for "new construction vehicle") were only available in 1933 as soon as the then Reichswehr gave a contract for the development of a Grobtraktor (heavy tractor) to both Rheinmetall and Krupp. Grosstractor had been a codename for the development of much tank, Germany being nevertheless forbidden to build up tanks under the regards to the Treaty of Versailles.
The 2 designs resembled both to a good extent, the primary distinction being the tools placement. Each had a primary turret armed with a 75 mm KwK L/24 primary weapon and additional 37 mm KwK L/45. Rheinmetall's design mounted the next weapon over the 75 mm KwK L/24, whilst the Krupp design had it mounted next to the 75 mm KwK L/24. Both designs had another turret mounted towards front side as well as the back regarding the primary turret. These turrets were somewhat adjusted Panzer I turrets, with the standard machinegun armament.
Rheinmetall's design had been designated the PzKpfw NbFz V ('PanzerKampfwagen NeubauFahrzeug V'), additionally the Krupp design the PzKpfw NbFz VI. It absolutely was intended that these designs would fulfill the role of heavy tank inside armored forces, however the design became too complex and unreliable for this part.
Developing however proceeded to enable the nascent German armed forces to gain experience with multi-turreted tanks.
