Jason, thanks for the note. I hadn't thought of disposable cameras. I got my sprocket from a 1950's Edixa rangefinder. Agfa Silettes and Argus C3 bricks also contain such solid-shaft sprockets. But disposable cameras are far more plentiful.
D316 is one of the early concentrates I created back in January, and Alan Johnson mixed it and has been giving it a longevity-test. Out of all the work I've done since then, it's still the winner.
