My random translations of the photo captions, clockwise from top left are:

• Lark Mini
• Lark Mini
• Eagle
• Lark Mini

The image at the bottom-right-hand corner is labelled 'Eagle' but is might be better described as a Shimano Eagle GTO.

So I think that the correct labels might be:

• Shimano Lark Mini
• Shimano Lark Mini
• Shimano Eagle GTO
• Shimano Lark Mini
