Trying to ID this crankset (well half of one as I don't have the left crank arm) if possible. Nothing fancy, probably some generic French set of little significance, but I quite fancy the look of it. Ring is swaged/peined to the crank and there are no maker's marks I can see apart from the pictured elements. Was thinking maybe a basic Stronglight but not sure and they normally have an "S" or similar marking. Comments appreciated......
