According to the NZG website, Gerhard Schmid and Betty Hauer started NZG Modelle in 1968, when the shop was set up in the second floor of a furniture company. The business soon moved to a 10,000 sq ft (930 m2) site at Sigmundstraße industrial estate. The first model produced was a Weserhutte wheeled crane, in that year. By 1974, at least 30 models were in the NZG range were noted in David Sinclair's Catalog (Sinclair's 1974). Sinclair, in the mid-1960s was one of the first importers to bring lesser known European brands to the U.S. (Levine 2009). Since then, over 700 different models have been produced and the company makes over 400,000 models a year.
In 1986 the company was operated by Inge Ludwig (née Schmid) and Hannelore Hauer. In 2000, NZG passed completely to the Ludwig family. Inge and Michael Ludwig run the company today.
Scales produced are 1:25, 1:50, and 1:87, as well as commercial vehicle models in 1:43. Special models require at least a 300 piece production order.www.nzg.de
