Surprisingly, I'm not finding a thread dedicated to this question. But I'm wondering if the Legacy chems are as identical to their Kodak counterparts as they claim. Some (unreliable seeming) sources on the interwebs suggest various provenance (produced in same plants, exact clones produced elsewhere, reverse engineered similar, not even close, etc.) Anybody know the true story, tested them with a mass spec or GC, or know from decades of experience that they are indistinguishable from the Rochester soups? I'm gonna try some out, but I'm curious to know the back story.
