This is the wonderful Tamiya 1/35th scale Panzer IVD, one of the best tank models on the market, thier IVH is even better!
The beauty of this model is that the Panzer IVD served just about everywhere, so you have a vast choice of marking/colour schemes to choose from. This model depicts a vehicle from the 21st Panzer Division (part of the Deutsches Afrika Korps) in Libya during 1941. The number 813 shows that it is from the 2nd battalion, and belongs to 8th company, 1st platoon, and is vehicle no 3.
A thick coating of mud was often applied to make the vehicle blend into local conditions, paintwork was often 'sandblasted' which let earlier colour schemes show through, and personal or crew kit was often carried on the outside, note the pithe style helmet, and the latrine bucket!
