Any cable experts online?? Whose cables are these?

They look like Audio Research Litzlink 1 cables from the late 1980's or early 1990's. I have only seen the brochure but they sure look like them. I own Litzlink 2 cables which were the more expensive version. These cables were hand made in house by Audio Research until a few years ago. Though I think the black litzlink 1 version may have been discontinued earlier. None of the ARC cables that I have seen have any markings on them. They used those smaller spades to fit the screws on the speaker strips Audio Research used back then.
