Develop before Nov. 1966

I developed some, took two tries to come out good - so I ruined a bunch of it. But I think I have at least one more box of 16 in the freezer. I exposed at ISO 50, and developed in D-76 for 13 minutes, agitate first minute, thereafter agitate for 30 seconds, then stand for 30 seconds for the duration. 2 minute water stop bath, agitating entire time, 5 minute fixer, agitate 1 minute, then same 30 second pattern as development. Film is very "floppy" compared to regular 4x5 so do not put film hold down clamp in tank, space film at least 1 empty slot apart from other sheets, and agitate by gently rocking tank back and forth.
