I had some Kodak DK50 in 2011 that was from the 1970s, and it worked fine (obviously). Right now I'm using some D76 from the 1980s, and that works just like the new stuff you buy today.
I have a case of DK50 in cans surplus from WWII. The military denoted it as Air Force Developer No. 2. Still very much OK. Still wish they packaged developer in cans. APAIK only the Acufine developers (Diafine ...) are still supplied in this manner.

A rock pile ceases to be a rock pile the moment a single man contemplates it, bearing within him the image of a cathedral.
