This is the Tamiya 35 096-1800 kit in 1/35 scale, of the ‘German Panzerkampfwagen IV, Ausf. D’.
The later models of the Pz.Kpfw.IV series have become the best known and the most fequently modelled variants. These were the tanks that took part in all the big tank battles of World War II and formed the backbone of Hitlers Panzer divisions.
