In 1926 advertisments proclaimed 'The New Meccano,' in fact in 1926 just 4 new parts where introduced, a 2.5 inch curved strip, the shortest of the longer bolts, a train coupling and a universal coupling. So what was so new? The answer was colour.
Up to this time, although there was some black, and brass parts, the overwhelming colour was silver (nickel). In 1926 meccano started painting there flanged and flat plates, trunions and several other parts red and there braced girders and the new curved strips green. The red was a bright red whilst the green was a light pea (pod) green. These shades of red and green though was shortlived with a new darker red - burgandy and a darker green was introduced in 1927.
This was also expanded to include most parts that could be coloured, notably perforated strips, angle and flat girders. Sets where tinkered with during this period with a quite a nujber of new parts introduced, In 1927 motor (Dunlop) Tyres where added. In 1928 Bevel Gears, the boiler and one of the most interesting parts the Digger Bucket a part which is today in high demand on the used market. 1930 saw more Tyres and a Circular Plate along with the very useful ball thrust bearing where amongst the introductions.
This period was marked with Introduction of some special sets, Meccano Aeroplane and Car Constructor had special parts resembling closely those of cars and aircraft to produce a more realistic model, whilst a new Elektron Set as it name suggests an electrical set along with Kemex a chemistry set was introduced. The main Meccano Range added a new smallest set no 000 although change to the other sets was very little except for the introduction of colour and a few parts the sets contents where little changed from the Nickel Period. A very short lived experiment was Meccano X with multi holed strips, made to rival the very cheap Trix system that was imported from Germany, the Meccano X being almost identical to the Trix system.
