The early Fiat 500s had the same tool kit but wrapped in a cloth tool roll. The roll was replaced by the grey plastic box which I believe carried over to th 126s. Earlier spanners have Fiat cast on them, later ones just a symbol. Wood handle screwdrivers were replaced by plastic at some stage with the 126s. On both types the screwdriver blade is reversible to give a flat or a cross head option. The grey plastic box was replaced on later 126s including the Bis by a plain but stronger black plastic box and the Bis had the addition of a black plastic tool which helped to locate the wheel bolts deep down in the wheel trims.
