I think my dad has a few unopened rolls of H&W Control. $10,000/each! He also has an unopened Kodak blotter roll
Thanks to everyone who responded. Anyhow maybe I'll just put my Technidol on ebay for a ridiculous price and see what happens. I never thought Technidol/Tech Pan was any good anyway. But let's not get into the document film nonsense in this thread. I wonder what other junk I can come up with? I'm pretty sure I have a box from some 1970s Rodinal somewhere (no developer, just the box ).
