Whilst a 14 y/o middle school student I chanced across a Modern Photography review on the then fairly new Leica M4-2 (June 1978 I believe) They said it was as well made as the prior models (cheaper ASA ISO reminder dial, stamped exposure indicator rather than engraved) I dug it out a shame no one does to an MP or M7 what they did back in the old, old days torture tests?

Engineering excellence is why they went to steel. smoothness of the
advance does not improved the pics. Plus it seems quite smooth to me, and
I've used M3's also. Who cares as long as it works reliably? It is alot
smoother than any Canon or Nikon I've ever had.

While this is all very good and interesting, it raises the issue of
relevance. You've had your M6 for 17 years. Let's assume that you put
200 rolls of film through it in a year, which means that after 3,400
rolls of film (122,400 frame advances) it is still not "broken in".
Personally, I'd be much more concerned with whether my M6 felt smooth,
efficient, and broken in *during* those 122,400 frames than whether it
would last another 1,000,000 afterwards. I'd even be willing to pay
$400 in repair costs for new brass gears, say, every 10 years if I
could have that buttery smooth feeling of an M3 in my M6.
I venture a guess that most Leica rangefinder owners do not shoot 200
rolls of film a year, many perhaps not even shooting 3,400 rolls of
film in their lifetime. The point then becomes, *why* it is necessary
to have gears that last 1,000,000 frame advances at the price of the
smoothness and articulation of that action, when few people are going
to use it that much? Why not offer steel gears as an option for those
who really need it?
This goes back to the issue that was raised a few weeks ago -- creeping
featurism. I should think that for the vast majority of Leica
rangefinder users, the steel gears is a moot point. Sure, engineering
excellence, but at the expense of quality of use. And isn't that what
Leicas are supposed to be all about?
