OK, the crankarms are dated September and October of Showa year 47, which was 1972. That's late enough in the calendar year that it's almost certainly a 1973 model.
I'm not sure what you by "specs of interest". The Tripping was a mid-range recreational touring model. There's not too much interest in C Itoh, even the top models.
