Years ago i bought some cable coils on Italian flea market in Lucca.
It´s a cotton insulated three conductor ( blue and brown /yellow-green) cable, pure stranded copper , no oxidation .
perfect to use as speaker cable or for vintage amplifier or tube radios as power cable- the cable is filled with gray cotton too.
Flexible after all the years .some terms of storage , the white color has some dirty parts , but looks great after all the time ...
