You simply cannot make any generalizations about bikes from any given country or from any decade. Geometries have always been very variable things. Also, you can't compare quality bikes with mass-market bikes like a Le Tour. Many of those kinds of bikes had no special "road bike" geometry at all, they were simply the same frames the companies used for their 3-speed "racers" but dressed up with derailleurs and drop handlebars. The closest approximation in terms of geometries today would probably be a hybrid converted to drop bars. But if you get a modern touring bike, you're going to get something that is roughly like what you're looking for. You could get yourself a Rivendell, but that would provoke extreme outrage among the hoi polloi on here, and it would be fairly expensive unless you're an affluent enthusiast.
