Re: 380b?
"Datsun's original production run began in 1931. "
The marketing story back in the 70s and 80s was that the original Nissan car was called the DAT (initials of the founders) and the next model was the "Son of DAT", aka Datson and they chose Datsun as looking stylistically better as well as alluding to the land of the rising sun. (which is also where the Sunny name is supposedly derived from)
