There is not much known about the real car, other than it is a 1906 Bianchi 15/20 Gran Coupè di Gala Otto Molle.
The real car is in the National Motor Museum in Torino, Italy. The car was also modelled by Rio as a 1:43 diecast.
Few people know that Bianchi in its heydays produced more than 200,000 cars per year and was Italy's third largest car company.
I have been looking for this kit for quite a while and I have the Mercedes counterpart:
Both kits were originally made by a company called Imai-Kagaku and ended up with Bandai through a takeover.
