This has already been done. Over on the Dye Transfer forum there's a fellow in Australia named Andy
Cross who precisely reverse engineered it, but he has access to true research lab facilities. It's a highly difficult product to duplicate, involving hazardous precursors. You can't do it in a home lab. Apparently Kodak no longer offers liquid developers in Australia due to hazmat shipping issues, so he
made himself a lifetime supply in a single batch. The concentrate allegedly keeps for decades. HC110
is still readily available here, so I don't know why anyone would even bother attempting to duplicate
it here, though I notice Freestyle claims to have an actual substitute.
iirc Kodak Australia doesn't import it, but we have no problem on having it shipped from the U.S. and receiving it. B&H has no problem sending it over.
