Need Help with Speaker Cable ID. What are they?


It has the following attributes:
-From the early 1990s
-Sold by a Vandersteen dealer
-Roughly the same diameter as Audioquest Type 4, but darker blue.
-About the same shade of blue as Audioquest Indigo
-The wire is stranded, not solid-core like the AQ family.
-No writing on the jacket.

Did Tara Labs make a blue cable? Is this a 90's "home install" AQ product?

In any case, thank you for looking and thank you again in advance if you can help me ID this product.
