Originally posted by stevebrot Sorry to contaminate your thread. I have read through your contributions several times and this is my uptake (finally!) plus what I found from additional research:
- The physical appearance of your Tak 58/2.4 is more similar to that of the 55/2.2
- You found apparent Tak 55/2.2 innards in your Tak 58/2.4
- Your Tak 58/2.4 seems to have a mix of parts including a curious aperture ring(s) variant.
- You have found a photo of an additional lens with similar features
- You could have made this much easier if you had provided comparison photos of your "true" Tak 58/2.4 in a line-up with the other two lenses.
The link provided by @Ned_Bunnell was very helpful in sorting this out since photos of the two lenses side-by-side were provided.
My belief is that you have discovered a new Tak 58/2.4 factory variant. This sort of discovery happens every so often with lens trim and body details*, but it is unusual to have other than the expected innards.

* I own an early Super Tak 55/1.8 that has a mix of features that were unknown before a survey on this site earlier this year.
This is on topic. Hence, no contamination at all. Reason I did not post photos of my own (supposedly real) 58/2.4 is that I only acquired it recently and that it went to my European address. I am in the U.S., so for the time being I won't have access to it.
I, too, believe that this is a factory variant. Either it is a "mistake" like a stamp error or it is outright fraud if it was purposely sold as a 58/2.4 but made like a 55/2.2. The aperture ring suggests to me that it is a mistake rather than intentional (if you'd fake it, you would try to fake it right; although the Rudy Kurniawan counterfeiters screw-up is a possibility). I do have a 55/2.2 to counter-check and could dismantle both including the front groups, but the similarities in construction that I have identified so far and importantly the identity of the rendering of the two lenses are sufficient evidence for me to claim that they are identical. Reason I try to avoid opening lenses is because it is easy to damage them cosmetically [not a pro].
So hunters of a M42-mount 58/2.4 should be aware and look for the ones with the correct specs: flat embeddedness of the front element, 2 feet MFD (not 1.8), very short distance between the 2.8 and 2.4 aperture markings, and (I suppose) no 154xxx serial.

Originally posted by Baard-Einar Prices are hard to understand... On December 11 a Tower 26 was sold with the 58/2.4. There is also another Tower 26 on eBay right now, shown with the 58/2.4. My own copy of the 58/2.4 also came on a Tower 26. It was the first standard lens for the AP, if I am not mistaken.
I don't have any facts to support which is the rarest lens of the two: 58/2 or 58/2.4. It ha been said that the 58/2 is really rare, but I have also observed a seller from Japan trying to move 5-7 copies of that lens via eBay for sometime.
I believe the Tower currently on sale is the same as the one that was just sold. If we are talking about the same auction, the person is selling only the broken AP body without the lens. S/he didn't even care to change the photos and take the lens off for an accurate depiction.

Originally posted by monochrome I have a AOC 1:2 Takumar 1=55mm with silver lens cap, Ser. Nbr. 150520 attached to my AP. I have it on good authority it is original to the camera but that’s just a story.
How can I help?
O.O If you have a preset (not an auto-) Takumar 55mm (!) f=2.0, I want photos or it didn't happen/doesn't exist.
Because that would be the second "new" lens we identify in this thread.
