I needed a 50mm LTM-M adapter, and found a really nice condition one at B&H. It is marked Leitz Wetzlar Germany DBP, M2 50, M3 28 50
Here's the thing. It works perfectly on my M3 SS and M3 DS. But it will not lock onto my M7, M240, CLE. It does lock onto my M4-2 and works ok, and while it locks onto my M5 it brings up a complete jumble of frame lines.
I don't have this sort of problem with any of my other LTM- M adapters (Voigtlander and Fedka) so wassup wid dat? I thought by buying a Leica one I would be guaranteed to owning one that would work with my Leicas!
I am putting this in the General section as I am trying to use it on film and digital cameras.

Could it be that it needs just a little extra turn clockwise. Sometimes it's a matter of less than hair thickness more turn.

Unfortunately no, it does not move any further.
Weird as my other adapters (non Leica brand) work with all the cameras.

The easiest thing would be to sell the M5,7,240, and CLE, then it will work on all your Leicas 
(I obviously have nothing of substance to add, other than I agree that it is odd)

It's possibly been hacked by someone in the past, and now the cam bringing up the correct framelines on all cameras does not its job properly. Look at it closely for such evidence. Or it may have been dropped. Does it lay 100% flat with no twist ?

No hacking. Issue with the cams is minor as everything works perfectly with the M3 cameras.
Issue is that it does not lock onto some of the Leicas. Guess I'm sending this back to B&H..

I also once had a genuine Leica adapter that experienced similar issues. I recall it had trouble locking properly onto the camera and when it did so was quite tight. I checked it once with calipers against another adapter and found that the metal was minutely thicker which I suppose threw the tolerances to their limit.

Perhaps it's not the adapter, but the various cameras' locking pin (however it is called correctly?).
Some of them are absolutely cylindrical, but some of them have teeny weeny bit corners, IMHO.

Misproduction. Happens to any brand.
Nice condition probably due to nobody ever using it! Just return it!

I seen this years ago, and kept (2) adpters depending on the camera it was going on in regards to showing up other frame lines. The ISBOO (28-50) you have will do that, and the IRZOO (50-75) will show different too. Try to pick up the IRZOO, than you will be able to switch to the particular "M" your using.

is the locking pin in the right place, sometimes it takes a bit more pressure with newer lens mounts.

Thanks for the comments everyone. I will return this one as it is the only adapter I have that is camera specific, and I don't want to deal w/ figuring out what's on what, I just want it to work!
I'll keep looking.

I always thought that it happens only to FSU production items, all other brands were perfect.

Yes, I thought that too...
Perhaps we should find a standard poor QC rant and cut and paste it but some fool will only believe it and then spread it around and I don't want that.

But is it poor quality control? Or the ultimate quality control as it says it is for the Leica M3 on it (see photo) and it fits perfectly on my M3s. Aaaaand on the cameras that it actually fits on it is the only adapter I have where the infinity focus mark lines up perfectly at 12 o'clock...

I wonder if it would bring up 50mm framelines on M2?

They use the same M mount.
My Summicron 50mm from 1952 works on my M3 and on my M240. Works on all my M mount cameras.
According to your theory it should only work on M cameras of the same era.

I had that issue with my M5. I happened with both Leica and nonLeica adapters by the way, so probably a camera issue?

Leica LTM-M adapter does not work on all my Leicas!
Blasphemy!
The correct solution: Keep the M5. Sell the rest. Return the adapter and exchange it for a different one. Take the M5 and lens with you to B&H. Test before leaving.
I own 3 factory original adapters and they all work with Konica, Canon & Nikkor lenses (35x2, 50, 85 & 135 mm) on my M5.

So you'd rather have me say the adapter was fine, but the standardised Leica M mount wasn't that standardised after all?
Whatever floats your boat, I'm cool with that too. My Leica II with a truly standardised lens mount
brings up the correct frame line with each and every Leitz viewfinder I stick onto it anyway
