It's not the innovation/development that I was referring to - I am sure that you are correct on that.
It's the styling: full chrome forks, with logo engraving
seat tube struts/stays, elongated (again with engraved logo)
rear quarter chroming, often with brake bridge painted (and part of rear derailleur hanger also painted)
I love the look - not something that I would associate with British bikes (we seemed to go for fancy lugs and lug lining which also give me great pleasure

).
Please be gentle - I have limited experience of bike styling, just my initial thoughts
