Synchrotone Bass Strings

[Paul Chick (EarthLink)]

List
 I remember some posts about Baldwin Synchrotone Bass Strings, but don't
recall:
    1. Did Baldwin discontinue them?
    2.When?
    3.Why?
Is there any information available on the history of wound strings, i.e.
when, who, what was used, how bass string winding got where it is today?
Thanks!
