It was more than 18 years since Nuts & Bolts Vol. 02 on the Wespe was published. It contained a short summary of the vehicle and brief descriptions to accompany the surviving vehicle photographs in museums and collections. Since then Nuts & Bolts has constantly evolved and improved. Historic photos, tables of organization and equipment, informations about the delivery of the vehicles to the units and the vehicle’s use in active service have been added. Every issue has these features together with 2D & 3D scale drawings, camouflage plates and a model section to complete what we believe is the most comprehensive study of each represented vehicle. Historically the Wespe” is an important addition to the German Army equipment and therefore we think it is appropriate to offer to our readers a totally new issue with all these additional features on the Wespe”. Additionally, the 10.5 cm leichte Feldhaubitze 18M, which armed the Wespe” and the Hummel-Wespe have also been included in considerable detail.
353 photos (198 historic, 40 model, 115 modern), 40 drawings, 13 camouflage schemes, tactical markings, table of organsisation (KStN).

One of the most interesting military vehicle developments of the German Reichswehr and Wehrmacht was without doubt the halftrack tractors. Basing on experiences from the First World War the development started at the end of the 1920’s. From the six types of un-armoured halftrack vehicles (1 tonne 3 tonne 5 tonne 8 tonne 12 tonne/ 18 tonne) developed from the early years and beginning in 1930, the main vehicle was the 8 ton halftrack Sd.Kfz. 7. This vehicle, which served in many differing deployments, and which had the highest production numbers, was produced from 1935 – 1945. Dr. Nicolaus Hettler, who has already described the halftrack vehicles 18 tonne Sd.Kfz.9 (N&B 12) 12 tonne Sd.Kfz.8 (N&B 16) und 3 tonne Sd.Kfz.11 (N&B 20), continues these series with the halftrack 8 tonne Sd.Kfz.7 (N&B 34).
