Hello I ve this Flektogon 35/2.8 with 14 blades ( instead of 12) and minimum focusing at 0,35m instead of 0,36m is it un curiosity ( rarity) or is it something modified ?
Thanks and sorry for my poor English

The last pic looks like there is some black touchup paint, is that what I'm seeing?
My Flektogon 35 in Exakta goes down to .35m, but there is more space between 0.35 and ft/m markings.
It also only has 12 blades.

Zeiss did a number of different versions and a number of different mounts, way more than I thought they had, when looking for a mint version without the wing/arm that Exakta usually has, took a long while to find it, seen a ton of variations, same with the Biotar 58/2, lots of versions, almost as bad as Helios 44, there is different mount styles in m42, different aperture ring markings(lines vs no lines), different aperture values(2.4 & 2.Cool, and yes, different MFD markings, I didn't even notice the aperture ring marking till I lined up my 35/2.8, 58/2 and 80/2.8 together, then I spotted a Flek35 like mine but it had T coating, which I didn't think was available in the body like mine.

Post some more pics of the lens, I'm sure the lens addicts group has seen a sizeable number of them, well let you know if it looks legit or not.

Th copy om m42lens.com also has a .35m cfd and has 12 blades, but there are also versions with nine blades. Different versions were made. http://m42lens.com/m42-lens-database/1547-carl-zeiss-jena-flektogon-35mm-f-2-8-16-alu-v1-12-blades

MFD and body is obviously possible and proper but 14 blades pose some questions and advise caution.

I know for 9 or 12 blades but mine is 14 and when I compare it with this photo i notice some difference : the front black rim is shorter , there is a red dot for the aperture selected and the space between aperture and selector is wider

The back of it is also different

I don't see anything that screams fake, just some unusual things, blade count being the biggest, but definitely not definitive, reduction of manufacturing complexity could easily explain the many variations in the mount area.
The blades look properly/evenly spaced, if it was customized they did a good job.

I guess the easiest thing to do is take some shots with it, if it's anywhere half decent it's likely legit.

I looked up the serial in the Thiele Fabrikationsbuch. This Flektogon 35mm F2.8 for M42 is ok. It is from 1953.

It looks like someone used a file on the rear section.
If that's the case it probably looked like this one:

https://www.worthpoint.com/worthopedia/m42-czj-carl-zeiss-jena-flektogon-414050406
Your serial: 3874927
Their serial: 3967002

You are very helpful, mine is very similar to this one event for the mfd (0,35m) and for the blades

I did photos few years ago and in my memory it was pretty good, I m gonna try it again if my eyes problems permits it

Is it more collectible ( valuable ) than a common one ?

I would assume it's a bit more valuable/rare being 14 blade.

What would happen if you'd put Flektogon front glass over Tessar lens design?
