Making missing elements

The cable holder for the handlebar stem (Ger. Kabelhalter an der Lenkerbefestigung) with the number 56 388 is present in the parts catalog of each "large OSL" model, i.e. in the 351/501/601 S/OS/OSL/OS WH models throughout the entire production period. So it should be a popular and common element in surviving copies of such motorcycles, ... and yet practically none of the owners of NSU motorcycles I know have seen anything like it or even seen it with their own eyes. So it's time to change it, because it so happens that I managed to buy such original elements together with a complete upper suspension shelf. So I took photos and a drawing that allows you to make such parts on your own, especially since it is not a big challenge. I think that complementing your motorcycles with such seemingly insignificant "flavors" distinguishes "true gourmets" of historic motoring.
