You might be better to try these questions in a photography group
if there are any that cover processing these days.
A call to Freestyle sales might turn up some old employee that could help.
You might also find some medical facility that still uses silver halide x-ray film.
From around 1960 through the late 1980's I was heavily into photography
and mixed my own chemicals from "scratch". I got the formulas from a
newsletter published by Patrick Dignan of Dignan Photographic in California.
He told all the things Kodak didn't want the customers to know :D
I don't remember much mention of line copy films, but he had formulas for
E-6,Anscochrome slides plus all sorts of B&W formulas. If you were really
a glutton for punishment (and had too much money) he even published
formulas and instructions for E-4. He took some side trips into DuPont and
other lesser known B&W films.
I did a bit of Internet searching and it appears a few university libraries
may have the collection in their archives. Mine is somewhere in the attic.
