This is a very unusual example of a blue hank of cord...The string or cord is very decidedly in a two tone livery! It is also a very large hank at 4.5" and again fairly stiff. It remains 1 mm thick but the overall length is again 184". Who knows were this came from? Could this be what is pictured in that 1926 nickel #7 set earlier? Hmmmmmm....
