I have a rather marvellous 400mm Telyt. It has a male 39mm O.D. thread which is bigger than the standard LTM. The normal way to connect it to an M series camera is to use a 16466 M which provides the matching female thread to a male M bayonet (23mm flange-to-flange), plus a Visoflex I or II which has M-bayonet to M-bayonet to connect to the camera and is 41mm flange-to-flange. The Visoflex houses the reflex mirror plus bits sticking out to set and trigger the mirror.
Now that I have an SL, I don't need the Visoflex. It would be nice to replace it with a simple 41mm spacer with M-bayonets on each side. i.e a dummy Visoflex. Does such a thing exist?
Alternatively I could replace both the Visoflex and the16466 with a 64mm spacer, 39mm female thread to male M-bayonet. Does such a thing exist?
The third alternative is disassemble the Visoflex. I haven't tried that. If I do, what problems might I face?

Dear Forum Members:
It is my first day here and I am already so happy that there is so much to learn and every one is sharing knowledge so enthusiastically.
I had a question about old lenses. On most lenses, when I move the focus to infinity, the barrel stops and I know this is the end of focus.
But the Telyt 280mm f/4.8 lens I have got (series number is 234XXXX) goes beyond infinity and extends to the m/feet mark. I am attaching a photo explaining the problem.
I have two questions:
Is this normal?
I am guessing that the Telyt 280mm f/4.8 lens does not couple with the rangefinder. In that case, I am going to be using the live-view any way.
Let's say, this is a calibration issue with the lens. Eventually, it should work out with the live view mode, right? Or could this calibration error mean that my camera won't focus in the right range, ever.

I've used my Visoflex 1 on my '37 Leica II, fitted with bellows, to take macro shots but I've just put it on my IIIf along with a 200mm Telyt lens to check it over before I take it out for some alpine photography in a few weeks time.
The problem is that although I can swing the camera through 90 degrees for portrait and landscape views, the camera is not horizontal or vertical, but off by a few degrees. This means that I can't get horizontal at all (unless I unscrew the Visoflex slightly), and I can achieve vertical but only by moving the camera off one of the Visoflex end-stops (I hope that makes some sense?!).
Can I adjust the 'end stops' on the Visoflex so that I can ensure horizontal / vertical setting of the camera? If so, how?
