For whatever it is worth, I imparted no particular value to this as a cosmetic item, but thought some might. Comsetically, it is a "design" feature, of value or not. Sort of like a "red dial" screw mount III -- some specific signficance to cogizscenti (? sp.), but not a huge one.
But, like the "red dial" designation, it also represent an engineering vintage -- time-wise, this vintage is slightly different from its successors - the meter system was occasionally funky, but the construct (Weitzler) was probably more akin to an M4-P than a last version M6-TTL, or certainly an MP. The German Leica repair guy who used to come around on Leica Days opined every year that he remembered this body, and it was a "good one".
Each M6 is really a bit different -- a different shutter release feel, a different shutter sound, and different pattern of adherence to shutter speed listings. Not much, but each has a personality. I had this one (early) and an M6-0.85, and I could definitely tell the difference with eyes shut. Some prefer the older, some the newer. I certainly could wish this one had an MP viewfinder, but it does not; otherwise it was great.
So, I hope no harm taken.
Of course, some would raise the old (but only sometimes true) argument that a family owned company has more pride and risk than a corporation, though I do think Leica maintained a very high road. The sale to Hermes probably had more effect than the 80's family sale.
By the way, some do say the Ford line did go down after the Ford family ceased to control it. That would be for others to argue, but Oil companies, drug companies, and auto manufacturers do lose some soul when the original wildcatters, scientists, and production line engineers are replaced by a strict M.B.A. Board who could just as well sell cosmetic widgets. They may, or may not, be better businesses, the product may, or may not, be better, but they are not the same.
I have a great fondness for this particular body, and part with it with some regret (of course).
