1430 cc? Hmm.... they must have been looking forwards to the Appia Furgoncino.
1,430 mm is actually the rear track, I'm clearly not safe to be let out without adult supervision! Make that 4,940 cc as the correct figure, same as the Kappa whichused the tipo 64 engine from 1919 to 1921 according to the wiki oracle. Perhaps if this is a 1920 engine it is Kappa rather than Triota?
