Can't believe there's no answer for this yet.
All others are pretty obvious, but cr. (ex. "NAT. BLK CR. TR.") could stand for cream but are there any other ideas? Nat. (or natural) is obviously some kind of white (correct?), but my old wire can't be that tan colored due to aging alone. So, is natural a white or a cream or a tanish white, or something else?
I think natural means un-dyed, so what color was the cloth un-dyed?
