surplus from the company I work for.  for doing a little searching this may be

at least the part number is the same.  if you search this part number and manufacturer you can find the specs.  the back of the tag makes it look like the total length is made of these pieces.  not sure, but either case most of the spool is there.  the tag says 1051 feet if that's correct there has to be more than 900 left  looks to be very little missing.
