When did Leica start coating their lenses?

Erwin Puts says:

Coating was also introduced on the military
versions of the lenses in 1941. The civilian production however did not receive this
treatment until after the war. The topic of the use of coating has not found its final
treatment. Rogliatti notes that coating had been applied to lenses from #587601
(Summitar) from 11 November 1945. The factory lists indicate that at 6 November
1945 the serial numbers 600000 to 601000 have been allocated for a batch of Hektor
13.5cm lenses. The first Summitar series begins with 603000 in early 1946. The
#number 587601 is part of a batch of Summitars from #586001 to 590000, allocated
in 1942! The factory archives in the optical department note that coating was applied
from October 1941 (from serial# 580000) and I quote:” from October 1941 all Leica
lenses receive anti-reflexion coatings. These lenses are not available for amateurs, but
only for war photographers (Kriegsberichterstatter)”. A report by the US Naval
Research Labaratory, dated 3 October 1946, on German coating methods during the
wartime does indeed note that Zeiss, Leitz and Schott all used several methods of
coating during that period. The report remarks that Dr. Männchen from Leitz
demonstrated an (experimental) method of centrifugal coating (as compared with the
Zeiss method of thermal evaporation coating), which however produced a very soft
Production was resumed already in June 1945 with serial number 595000: a batch of
1001 Elmar 1:3.5/50mm lenses. Between October 1941 and June 1945 Leitz
manufactured about 15000 lenses, and some larger batches were reserved for the
specialist lenses for military applications, some of which were very rare, like the
IRTessar 5/5000mm. It is reasonable to assume that most of these 15000 lenses
went to the government. As it is also very likely that not all lenses, produced before
October 1941 were sold out at that date and Leitz would be able to provide amateurs
with the non-coated version of their lenses.

$1500, not $500.
Yeah, I was referring to bodies, as all cameras today are sold that way...

And that's not a lot of money today...

They are interesting, considering that I've been moving away from uncoated optics. Occasionally, I do have need of a 35mm camera for more "candid" images, where mirror slap would be a problem. A leica would fit that bill. That said, I can't afford one.

Also, I read about the refillable Quickloads on LF.info, and it seems like a good thing. Apparently, they need some startup money.

You can hear how James Ravilious modified his Leica Lens-Hoods on this short film on YouTube. http://www.youtube.com/watch?gl=GB&hl=e ... Yg8mxvUgJE
Back on the topic of Quickloads, the refillable Quickloads and Readyloads would be nice for 4x5 users.
