Description
Over years of production the same model may have been produced with many variations. We typically use Koll's numbering scheme to identify them. Keep in mind Koll's last volume for Z was published in 1997 so we're likely omitting variations we're unaware of since then.
Coupler type: Koll refers to the earliest coupler design as Kupplung 1 (type 1), typically 1972-1978. This was replaced with Kupplung 2 (type 2) in 1979. The top surface of the latter is beveled towards the point of the hook. In some cases the type 2 coupler came into play as early as 1977. The first picture is type 1, the second, type 2.
Wheel type: Koll calls the early wheel design Kunstsoff-Vollradsatz - full plastic. These were the norm from 1972 to 1973. They were replaced in 1974 with the Kunstsoff-Leichtradsatz or lightweight plastic, version and used through 1979. In 1980 metal models came with metal wheels. The first picture is "full", the second one is "lightweight" - based on the structure of the back of the wheel.
