In 1907 Elliott and Hornby set up a factory in Duke Street, just a few hundred yards away, for the in-house manufacture of most parts. The Meccano name was registered on September 14. In June 1908 Meccano Ltd was formed. The former alphabetical Mechanics Made Easy Sets X to E were now marketed as Meccano Sets 1 to 6, and a different key fixing for wheels obviated the need for grooved axles - the new system was, however, less positive than the old. Meccano strips now had the familiar rounded ends, and being made of thicker steel, were without folded edges. Nickel-plating replaced the former tinplate finish, and this was to remain the standard finish for most Meccano parts until the introduction of the "New" coloured Meccano in 1926.p

Meccano Ltd. moved again to a factory in West Derby Road in 1909. Sets 5 and 6 now came in wooden cabinets, the largest set containing no less than 168 121/2" Perforated Strips and 245 Angle Brackets. Just one more Angle Girder was added to the system, 51/2" long. In 1910 the Hornby System of Mechanical Demonstration was introduced for use in schools, along with the larger Flanged Plate and the 4" long Flanged Sector Plate. Stamping of some Meccano parts began in 1911, and by this time the first "downsizing" of Meccano sets took place - the 1911 No. 6 Set, for example, had only 48 121/2" Strips as against the 1910 set's 168, and 500 Nuts and Bolts as against 950. Meccano (France) Ltd. was established in Paris in 1912, and the first Windmill Sails were introduced. In Germany, Marklin began Meccano manufacture under licence - this association is now remembered mainly for the No. 1 Marklin clockwork motor and the remarkable, and highly prized, three-output-shaft No. 2 or "trinity" motor. Up to this time the securing of wheels to axles still relied on key fixing : the change, begun in 1912, to the (single) tapped boss and set screw system must have met with universal approval - it represented the turning point from which serious Meccano modelling became possible, free from the limitations associated with a fundamentally unsatisfactory, and what must have been a very frustrating, method of fixing of wheels to axles. The total number of different parts in the Meccano system had now grown to about 60. A recently discovered Windmill Set has been provisionally dated at 1913 - as such, it is the first known "one-model" Meccano set. Having outgrown the West Derby Road site, yet another move was made during 1914 to a purpose-built factory at the address which was to become familiar to generations of Meccano boys the world over: Meccano Ltd., Binns Road, Liverpool 13, England.
