DISRAELI GEARS
Dai Nippon Bicycle (DnB) were a Tokyo based manufacturer of bicycles. In the 1950’s there seems to have been two centres of bicycle industry activity in Japan, Tokyo was one, and Sakae near Osaka (the home of Shimano, SunTour, SR and Sugino) was the other. A certain Mr. Miyata (a name with resonance) from DnB seems to have been an influential figure in the Tokyo group.
Derailleurs branded DnB were produced by a company called Dai Nippon Kikai Kogyo Co., Ltd, which was presumably the same as or related to Dai Nippon Bicycle.
The history of DnB derailleurs is a little unclear, but may go like this:
On a different point, I am vaguely suspicious about how various other brands relate to each other:
