On the other paw, if you can get Kodalith in 70mm double perf then the

good set (matches the C11 or C13 sender).)

No, but I got a bunch of Tri-X in 70mm with Type I and Type II perfs here.
Might have something higher contrast too. How long is the strip? You
ought to be able to contact-print it if it's not too long.

70mm Type I is still very popular for aerial photography. I don't know how
much longer that will continue, though.

If the filmstrips are brittle, you might consider using Filmguard on them.
It is very good at softening up old acetate films; I have had 35mm prints
that were stored in attics and could not be projected which, after being
soaked in filmguard and left for six months, softened up nicely.
