I picked up a used line spooled on a generic spool with no ID other than the following marking:

C-7PT-NT-WF3F-DO

Anybody have any idea as to what brand it is? I realize it a weight 3 weight forward floating but what are the other markings mean?

May just mean something personal to original owner. I Googled it and could find nothing. The line is a dark olive green color.

Thanks,
Dave
