This neat and stylish brochure was published by a Japanese brand whose 'S' type logo looks familiar - but I have forgotten their name. I shows three 'touring' bikes, two of which have 15 to 21 T freewheels - those 1960s Japanese cycle tourists had strong legs.

The derailleurs appear to be as follows:

• The top-of-the-line MC model has a Sanko PA derailleur (you can see the PA in the fourth line from the bottom of the specification).
• The KW model has a Simplex Prestige derailleur (you can see 'シンプレックス', which may be the Japanese for Simplex, in the third line from the bottom of the specification).
• The ATC model is a bit less clear. There is an 'F' in the third from bottom line so my best guess is that it is a Sanko F1. If you can read Japanese please let me know the truth!
