Yeah, right.  I was out the other afternoon with an M3.  Noticed, without
much thinking about it, that the eyepiece was loose (thanks, Ted).  Out of
curiosity, I screwed it out.  Cleaned the glass, and screwed it back in.
For this I need a "special" tool?  Maybe the torque's critical.  Could
induce spherical abberation or some such thing.  I reckon the DOD and Leica
confer on prices for tools.  How about US 278.98 for "eyepiece wrench,
Leica, chrome beryllium, MILSPEC 001556600?"
