Mercury (toy manufacturer) Marklin, the company was started in 1932, by Attilio Clemente and Antonio Cravero, but its first toy was a gun produced about 1939 (Batazzi et al 1974; Force 1992, 5; History of Mercury 2013; Ralston 2009, 62). The company first began making toy cars just after World War II, so is one of the earliest diecast model makers preceding Corgi and many others and it was the earliest producer in Italy (Richardson 1999, 134). In Italy there was little competition for Mercury through most of the 1950s (Force 1992, 5). Early cars were more Tootsietoy-like with simple cast bodies, wheels
Spekkens toy model mechanics, as there are fundamental differences between the model and quantum theory. In particular, the model is one of local and noncontextual variables, which Bell's theorem tells us cannot ever reproduce all the predictions of quantum mechanics. The toy model does, however, reproduce a number of strange quantum effects and does so from a strictly epistemic perspective; as such, it can be interpreted as strong evidence in favour of the epistemic view. The Spekkens toy model is based on the knowledge balance principle "the number of questions about the physical state of a system that are answered must always be
