The 14167 offers M-lenses to R-camera. BUT that means, that one can take macro photos only.

With the 14127f, one can use the special Visoflex lenses on an R-camera.

Both the 14127 and the 14167 were meant to use Visoflex lenses with an Leica SLR camera. With the 14127 you had to set your chosen f-stop on the adapter which was read by the Leicaflex to allow lightmetering. The later 14167 was for the later SL- and R-cameras and didn’t need and have the f-stop settings on the adapter. 

To use a 20cm Telyt lens you have to leave off the Visoflex I housing and use an OUBIO/16466 adapter which has a 39mm thread-mount on one side and an M-Mount on the other, so you don‘t need an LTM-to-M-adapter. You can fix this to the 14167 and so use it on the R. 

I even tried this combination (Telyt, OUBIO/16466, 14127) and an R-to-M-adapter to use it on an M with Liveview. It works in principle, though it shows vignetting which isn‘t there when you use a Visoflex housing as an adapter.  

You may see the combination here (second photo):

I have the 400/6.8 Telyt-V which I use with a 14167 and then R-M adapter on my M240.  I found that it corner-vignettes visibly with the current Leica R-M adapter but no vignetting with the Novoflex R-M adapter.  Looking into the adapters I can see the physical difference in the throat opening which would account for the vignetting with the Leica-brand adapter.  The disadvantage to the Novoflex is it has no tripod foot but in the case of the 400/6.8 it has its own foot.  I also use a 70-210 f/4 Vario-Elmar-R , and that one does not vignette with the Leica-brand adapter.
