any isolation platform sleuths out there?

Hi all - I came across an isolation platform in storage, under a box.  I don't think I've looked at it for 20 years, at least.  It's 3/4" x 19" x 15", black, with almost a herringbone pattern on it, below the finish.  it's actually lots of little tiny grey and black rectangles.  if I remember correctly, it's made with some aerospace polymer/material.  for the life of me, I can't remember the brand.  any thoughts?  20-25 years ago you'd see these here on audiogon from time to time, but my interweb searches now have revealed nothing.  any help would be appreciated.  ct

Pretty sure I have one under my DAC - Black Diamond Racing - The Shelf, although could be The Source.  Here is one that was previously for sale.

thank you - that’s it!  with the thickness, it’s The Shelf.  Now to try to figure out its value - looked it up and CAD $1,100 new. Mine is in rough shape cosmetically, but obviously near perfect shape for function.  forgive me - just musing aloud. Thanks again - I really appreciate it. C

Here you go...

This site should help. I filtered by units sold in the US. Keep in mind the "asking" price is the price that is listed.
