How Were Sunbursts Made?

How were these Tiger Eye style Sunbursts made? The results of the lawsuit Akro filed against Master suggest that Master was just using one pot of glass and not injection. How could these come about with those conditions? I am mystified.

According to the Akro vs. Master case text:

Akro injected two seperate streams that consolidated into one stream w/ colored glass on the interior only and clear glass surrounding the colored.

Master's machine only dumped colored glass into a pool of clear glass without control of the colored glass and without a separate pot of colored glass. Also, Master's colored glass was not wholly within the clear glass and there are no separate streams of clear or colored glass.

Scale appears to be not in any way accurate. . Are there 2 furnaces and this is the area of the gob feed system were the 2 streams of glass come together at the shear.Hoe did the glass get to these 2 areas???? Or is all that apparatus inside a single furnace(looks possible)(complicated crucible system a tiny bit similar to the Jabo type crucible set up) I would think at that time any of the materials touching glass or in the furnace would need to be some type of ceramic. There are patent pictures of multiple tanks with Akro cork set ups.

These pics clearly show we have a case of several furnaces and I believe just a ceramic rod that extends out of the crucibles in one furnace holding the glass to be "injected" to the mechical parts outside, The base glass(Clear) is in one furnace and the other colors are in the injector receptacles that sit in another furnace. The very last pic shows several streams from seperate furnaces thought to deal with the Corkscrews.
