Another popular cycle marque around here in the early 70s was Favorit, a Czech maker.
While most of their cycles were rather ordinary 10 speed tourer/racer style, their high end racing bikes were made with their own butted tubing and a number of their own components. I still see them around town, 30 years later.
Speaking of history, as the Czechs had just finished rebelling against the Soviets a few years earlier, frankly I am more impressed with their efforts at high end cycle manufacture than I am with a huge company like Schwinn, in a USA that was sending landing modules to the Moon at the same time as building Paramounts.
