Later copies of this set (sold beginning in 1982 or 1983) replaced some parts with newer mould versions and redesigned a weak joint in the driveshaft. These changes resulted in the part inventory being reduced by 2 parts.
The set's building instructions include detailed instructions for the main tractor body along with two alternative instructions for a plow or a harrow as the rear attachment (there are only sufficient parts included to build one of these attachments at a time). Additionally, the instructions include:
* Detailed instructions for an off-road racing vehicle B-Model
* Pictorial instructions for motorizing the tractor using either the European set 870-1 or the North American set 960-1
* Detailed instructions for building three additional rear attachment options using parts from set 8710-1
* Pictorial instructions for building two additional B-Models - a Dune Buggy or a Beach Bicycle
I am definitely on board with a little background commentary on some of these models. Thanks!
