I can help you...have several 3 cam lenses. But I'm heading out the door at the moment...yeah, to work. Sometimes in this economy it is necessary even when one is retired!
Email me direct as a reminder and I'll get out the calipers and lenses this evening.

Tim, I measured my two cam lens with the following results:
A. 45.98mm
B. 48.95mm
4. 59.6mm
The above are the average of the readouts on my digital calipers. Actual reading varied as much as .02 plus or minus.
It will be good to learn what Henry gets. |

Let's see here...on a Leica 50mm f/2...
A = 1.811" = 45.9994mm
B = 1.929" = 48.9966mm
4 = 2.348" = 59.6392mm
Leica 35-70mm f/3.5
A = 1.811" = 45.9994mm
B = 1.929" = 48.9966mm
4 = 2.347" = 59.6138mm
The only difference I found between the two was .001" on the R dimension.
Have fun.

So to compare David's and mine...
A = 1.810" for David's
B = 1.927"
4 = 2.346"
David's is about .001-2" smaller everywhere. This could even be the difference in our two dial calipers.

Thanks so much for all your help..
I do have one more question regarding
this... Is the actual Top Dead Center (TDC) of the lens at 12:00 in the picture, or is it rotated.. (if so, CW, or CCW, about how much?)
Thanks again,

Yep, pretty well looks like TDC to me.
Btw, what are you doing? Why you need these dimensions?
