John:
Now the situation looks different, 10 no sold TLR Rolleimots
were adapted to test the new camera Rollei SL 66. The same info you
obtained from Prochnow's SL 66 booklet is available in the Rollei
Report 2, page 26-548 where you can see the SL 66 Rolleimot
photograph, I had seen the image and read the image caption but I did
not read/translate the text beside the photograph, it contains the
same info than the booklet. Interesting the part where Prochnow
comments the Rolleimots no longer worked after a few thousands cycles,
much sooner than the camera and they needed to complete the tests
working by hand in three shifts, round the clock
I smiled thinking about the lion and the jammed Rolleimot...
