Synergistic Research question

I was recently given a pair of Synergistic Research Resoluton Reference interconnects. They are older interconnects and I can't find any info on them. They are .5 meters, have a black weave with two white strands woven into the jacket. On the input end one of them has a red band around it, on the output end one has a black and a blue band, the other is red and blue.
Anyone have any info on these? How old they are, are they anything out of the ordinary etc.

Thanks for any input.

Dave
