Thank you for the additional feedback and tips, I somehow missed them at the time sorry.
I didn't trust myself to proceed further and the alignment was too far off to ignore. The camera is currently still with a local and very trusted (former Leica employee) repair person.
It is a very lovely little camera Erik, I did even have two of them briefly and that's the only image of the top of this one that I have currently.
The 'K' model at the top had the incorrect shutter dial fitted, such that it didn't match the shutter speed indents correctly and was just impossible to use practically. So I returned it as it was as expensive as you might imagine.
The one I still have, at the bottom, I was lucky enough to have found for a reasonable cost. The number 8 is painted oddly on the top, could the numbers have been retouched? If they have the paint is a perfect match.
The IIIc 'stepper' feels noticeably better in practical use to me than my IIIf, the tiny differences in size seeming larger in the hand.
