The state court trial must have been transcribed before Marvel removed the fight to federal court. Just where those transcripts are now, 60 years later, is hard to fathom. And of course, if you had the transcripts, you'd know who offered your piece into evidence, and for what reason. It's hard to believe, but some things are simply lost in the mists of time.
I do know, as I'm sure you do too, that Simon and Kirby worked together on Blue Bolt before Simon came up with the idea for Captain America. Your piece is somehow referencing that. But that's likely as close to the truth as we can now come.
