John,

I think the key to the identity of the brand name of the thread is the blueish color of the spool the thread is wrapped upon. None of my threads have that color. I did a search on the internet and looked at hundreds of photos of threads; none have that color of spool.

It is possible that which ever company made that thread either no longer exists or switched up to a more modern spool and color assortment.

Good luck in finding the thread. If you do locate it, would you let us know what it was?
