LEGO® Supplementary Set

Description

Parts for extending

A supplementary set is not a model but a box of parts: it widens the stock for constructions begun with basic sets. This one dates from 1977 and runs under Technic / Expert Builder, the early technical range from which the Technic world later grew. Anyone wanting to build functional models with moving parts received extra elements to work with. Today the set mostly interests collectors of early technical bricks who like to keep the whole range in view. That it is a stock rather than a model also explains the sober name of the set.

Light grey, yellow and black

The main colours are light grey, yellow and black. That suits the character of a technical range: sober, functional and easy to combine. With 78 pieces in 22 types, the selection is modest. This means individual types appear several times, which helps when building frames, axles and superstructures, since you often need identical elements more than once. Without minifigures, the technical idea clearly stays in the foreground. The small number of colours also gives a uniform look that is easy to mix with other technical parts.

Who the set suits

The set is aimed at anyone wishing to top up a basic stock of technical parts, and at collectors completing a catalogue of early material. It is less a toy in the classic sense than a kit for ideas. With the parts you can develop a chassis, a mechanism or a frame, which you then clad with bricks of your own. The appeal lies in experimenting and understanding how individual building elements work together. Once you have designed a mechanism of your own, you soon understand why such supplements were so popular back then.

Using the parts list

You will find the complete parts list on this page. Compare it with your stock and check what you lack. With “What can I build?” you can also discover which models your bricks already allow. Light grey, yellow and black parts are common in many collections, so with the right bricks you can often recreate something similar, even without owning the original set. That makes this page a practical reference when you plan a technical project and are unsure what is still missing.
