The Weinmann QR system you are describing were installed on probably millions of Euro bikes in the 70's and early 80's (I think my 1983/4 Peugeot PH10S might have had it too...can't remember). It was a clever idea that worked OK most of the time on mid to lower model bikes, but It pretty much dissapeared with the "turkey leg levers" after the mid 80's. Better brakesets with more sophisticated cam type QR systems were coming out of the far east that eventually supplanted Weinamnn's lower market niche in the bike industry. and killed off these old tech designs for good.
