Would anyone have any idea how many of these cameras they produced? I heard that they were down to 50 copies a month produced at the end of the run, but no mention of how many they might have produced at their peak.

<p>Thank you. I had found those before, but they don't really tell me how the timing mechanism works or how timing is achieved.</p>

<p>Is there a pdf or good instructive source on how mechanical shutters are constructed or built? I'm trying to understand exactly how the timing mechanism works on the older type shutters, like Copal etc. I've not been able to find any technical material online except for repair manuals, which don't really helps me understand the mechanisms.<br> Thank you.</p>
