Those of you understand the mechanics of rangefinders I have a question. I have purchased a second Ikon. I noticed that it will not lock my CV 28/1.5 into place.
It will mount the lens and I can turn it all the way over, but the last millimeter or two it simply will not lock. The frame lines and focus are engaged.
Upon inspection of the mount, I see 4 pins and on my m-body’s throat and I see 4 blades on my lenses that fit into those groves. I see that one of the pins is not in the grove (see the 2nd photo). The other 3 pins in that camera are tucked into the grove. My other Ikon, which mounts and locks my 28/1.5 without issue looks like this with the pin tucked into (see 1st photo).
Is the unengaged pin on the new Ikon hindering the lens from locking?

Is it difficult to get back in? Have a link or explainer on how to do it?
The camera is actually in pretty good shape—but lol on the spider indeed.
If I remember correctly, it's only screwed down on one side, so you should be able to rotate it enough to slip it back under its anchor. Use tweezers and try not to crease it while bending.
I have noted the same type of issue with third party lenses especially M4-2s, with two them even after both CLAed by the best people, still have issues of locking some third party lenses, although every Leica lens from 1950s build to present easily lock. It is not uniform for instance a few LLL are difficult to lock while others lock easily, so isn't simply the make of the mount, the Funleader 45/2 locks on some and not others, and some Voigtlander can be fussy to lock. I have noted the same using a Voigtlander Bessa seems to lock Voigtlander lenses well enough, but can be fussy on others. With quite a few film cameras there are some lenses I will not use on some cameras out concern of dropping the lens off at the wrong moment. Among the Leicas my two M4-2s are the most fussy about not locking some lenses, M3s, M4s and MPs are often but not always much better. I always test a lens on the camera of the day, so there are no surprises when I am out or worse, damage. I have tested perhaps 30+ different lenses on cameras and there are issues, with the M4-2 being the worst offender.

Removing the mount on an M wouldn't get you any closer to loosening the anchor screw to put the spring back in place (without bending it) and then tightening it down. A loose anchor may have been in the problem in the first place. To repair it right like that, you'd have to open it from the back. Sorry the cheap fix didn't work out.

Yup—I removed the mount but just as you say, no access. The the repair place explained it as you did. Hence the $450.
The seller paid for it—he sent it broken which was not as described. If it were my $450 I would have been more sad.
