  Dan - etal

  Leitz used to mark their 50/3.5 Elmars with a # from 0 to 9, standing
 for 1/10 of a mm (true focal length as opposed to marked FL) and even
 earlier, the model 1(A) & 1(C) had a peephole in the rear of the body,
 which could be uncovered & a magnifier was used to check the aerial
 image & focus was compensated for by shims. Longer lenses had the
 true FL written inside in pencil.
   Of course this was before diecast bodies & improved quality control
 of today (supposedly) and that is why I am so adamant about QC.
 There is no excuse for the M6 plastic gear debaucle regardless of it 
 being made in Solms, Wetzlar or Portugal.  Leica ought to offer a free chk
 so that the stigma would be gone regardless of the statistics which can
 be compiled to make any point; pro or con.
