If you're interested, I have a couple rolls I could part with if you still have any of the Agfa left.
I have two rolls of Kodak Ektachrome 50 Tungsten and one roll of Kodacolor 400.
The Kodacolor expired in 1/1981 and the Ektachrome in 02/1984.
That's the only old stuff I have that's in individual boxes that I'm also willing to get rid of.
I have some Provia that expired in 2002, but I imagine you can easily find that anywhere on your own.
If you're not too picky, I can hook you up with empty boxes/spools/backing paper for some old (80s) Ilford Pan F, but I use the film often and it would take something very special to get me to part with any of the actual film (I only have about 2 bricks left).
Also, I may be in LA in a couple days, so I MAY be able to meet and trade in person to avoid shipping for both of us.
