All that link did was take me to Efke 25. Is that what your talking about?
Look again, its 25 orthochromatc. ordinarily the only stocked 3x4 I know of
is EFKE 100 at Freestyle (at least here in the states)
its nice to know there is more than one option without having to wait for
Ilfords ULF run.
If there is more that I'm not aware of I'd like to know about it
