“A guide to shooting expired film” from PopPhoto

Today I received in the mail a Graflex Super D with “automatic diaphragm”, and more relevant to this article – a graflex pack film holder #523.    I have never seen one of these things before – it’s a metal box that has 12 or 16 sheets of film inside that allows the photographer to advance to the next sheet by pulling on a tab.
