These are the two instruction leaflets that came with the post-1971 Set 100 and Set 200. These sets were identical in quantities of parts to the old Set A and Set B. The Set 100 instructions introduced a few new models such as the Lifting Bridge and the Tractor, whilst losing a few such as the see-saw. The Set 200 instructions however were completely revamped with a completely new range of models compared with the old Set B.
