As I do not read Japanese, it is difficult for me to make too much sense of this, rather elegant, catalogue. Based on very little evidence I guess:
I am more than a little unsure about my contention that the derailleurs shown are the Shimano 333 touring model. This Shimano derailleur was extremely similar to various Cyclo, Huret and Simplex models of the time (it would be rude to use the word 'copy'), and it is also possible that other Japanese derailleur manufacturers produced very similar designs. My identification of the derailleur is based only on the blurry photographs - perhaps someone who can read the text can correct me!
