What can we tell from this entertaining document? Some things might be:
The Italian authorities enjoy the use of a rubber stamp (used 14? times on this document).
Rino Radaelli appears to have been doing something with his distinctive Rino copies of SunTour derailleurs as early as 1979.
Rino Radaelli had clearly attended the Salvador Dali School of Technical Drawing.
I don’t read Italian, but it seems to me that, in 1979, you could be granted an Italian patent for ideas that you had clearly stolen from SunTour. Perhaps, in the tradition of Marco Polo, the Far East seemed a very, very, long way away.
