I agree; it's painful to behold from an adjustment point of view. They're not a bad glass optically though, I had a military here one a couple of years back. Why it took the USAuntil Vietnam to get their act together on rifle scopes when they were one of the countries that pioneered their use is a bit of a mystery. Lost in the corridors of the War Department in Washington I suppose.
However, look at the Germans with the ZF41 and Zeiss Zeilvier, the Kahles and all those others until the ZF42: no clicks, no markings you can read from a firing position and no windage drums either. Even the Soviets figured out you needed to be able to read the markings without having the thing across you lap, but then they forgot the clicks until the PU came out in 1942.
Give the old 32 MkI its due, for all it's extra weight, missing backlash springs and sloppy detent plungers.
