Hey Zeiss-junkies,
referring to the orignial question about Zeiss and M42, here's some more stuff to read if you are interested,
Carl Zeiss Jena East German M42 lenses:
PRAKTICA-USERS.COM - M42 Lens list
Most complete M42 lens list:
M42 is a site dedicated to M42 adaptator lenses. You will find here tests, from argentic to numeric cameras and oldest to newest M42 lenses. Members described their work and the used lens. Oldies, but goldies!
So, you are getting most Zeiss M42 from the East German Carl Zeiss Jena (and from pre-WWII-time).
However, there are some from Carl Zeiss West Germany also. AFAIK, these have been produced in the 1960s for Voigtländer and Rollei cameras, who at a certain point have had a joint-development camera (The Voigtländer VSL1 aka. Rollei SL35ME). Not a pretty camera, but: the Rollei version was only in Rollei mount, whereas the VSL1 was also available in a 'TM' (thread mount) version. This is the M42-version, and the old lenses for this camera have the name print 'Carl Zeiss' on them. Don't know if they are too cool for school cause they've come out before the multi-coating era. However, there are e.g. different versions of the Standard Lens Ultron, and the second version with concave front lens is kind of a sought after thing. The third version Ultron M42 is named Voigtländer Color Ultron 1.8/50 and that's the same as the Rollei HFT version. It is kind of 5-10 euros for the Rollei version and around 100euros for the Voigtländer M42-version, so you pay for the M42-hype. Beware, the Voigtländer comes in either Rollei or M42 mount and look otherwise the same,

The other naming is an engraving on the backplate, and there it says either Made in W.Germany or Singapore.
Sorry for long text but I found it so confusing to get this info and I hope it's not too clumsy to read it.

edit: Shame shame shame, forgot the Zeiss Ikon cameras! For example, "Zeiss Ikon Voigländer Icarex...". These had bayonet and M42 mount versions and there you had the west german M42 Zeiss lenses on them.
Frank Mechelhoff/taunusreiter.de -
(english translation) states that the lenses were worse crafted than the Asahi-Pentax Takumars, which just goes to show that Takumars are in many ways the pinnacle of lens-make til today, well deserved!
Here's is Frank's list of Zeiss lenses for these cameras, which he states have all had M42-versions.
* Distagon 4/25mm
* Skoparex 3.4/35mm,
* Panthar o. Tessar 2.8/50mm,
* Ultron 1.8/50mm (mit eigentümlich konkaver Frontlinse),
* Dynarex 3.4/90mm
* Super-Dynarex 4/135mm
* Super-Dynarex 4/ 200mm
* Telomar 5/400mm
* Zoomar 36-82mm
