In 1945, after leaving the armed forces, he returned to Turin and after a brief period at the Mezzenile sawmill selling wood, and a short work experience selling utensil machinery, he started working in a small toy factory, Inco Giochi, starting in September 1947. The company had the feature of the toys being completely built within the factory without any external production. Also, unexpectedly, it did not possess an effective sales network with agents. The “Industria Costruzione Giocattoli” was born in Turin in via Pietro Giuria 39, in 1946: it focused on the production of toys, train sets, boat and tram models made out of bent lithographed metal plate. They were sometimes made in zamak, a zinc alloy which can unfortunately deteriorate with time.
When Alessandro arrived, the portfolio included just one item, a wind-up spring Frog of German origin; all the following articles were later conceived by Alessandro who immediately proved his skill as a designer and drafter, but not only. Completely single-handedly, he managed to design the toys , creating hand-made prototypes, designing the necessary molds and lastly applying them manually.
Therefore, to all intents and purposes, the Inco Giochi catalogue dated 1947-1949 was the work of Alessandro Quercetti alone and included: a Mechanical Frog (redesigned and improved with the wind-up spring), a Horse with the native American White Feather, a single room Turin tram with a ring circuit of rail-tracks, a double-room Turin tram with bellows and double-circle rail-track circuit, yellow single-chamber Turin-Milan Motrice Littorina , the single-chamber Milan-Venice Motrice Littorina in two versions, yellow and blue, the double-chamber Turin–Milan Motrice Littorina with bellows, also blue, with and without lithographed characters, the Aldebaran motorboat, a Tractor, the Inco Sailing boat, also fulfilled in a special version for Pasta Agnesi, the “Automotrice Express”, the “Automotrice Continental”, the Tram Circuit, the Otto Tranviario , the 685/A Train also produced for Rivarossi.
However, within two years, the factory suffered a crisis for financial reasons, and not having received any wage for many months, Alessandro had no choice but to resign, officially leaving the company in September 1949. Yet he continued to visit it for some time after, thanks to an agreement with the two owners who allowed him to use the machinery for the creation of some cogs (gears), which he needed for a future toy he was designing on his own.
