Just for the record (based on my recollections of a Reid from 35 years ago), the TTH lens was basically a motion picture lens (I believe it was originally called a Speed Panchro). As I recall, it was arguably the sharpest lens I have ever used (compared with the many Leicas and Nikons I have also owned) over a area somewhat larger than the 18x24 mm of a standard motion-picture frame. The edge definition on a 24x36 mm frame was however not great at large apertures, and even with the lens stopped right down, the edges never quite matched the center.
