I recently acquired a Schneider Symmar 180 mounted in an Arca-Swiss Automatic shutter unit but haven't had much luck finding anything about the shutter. There's a battery compartment and a 5 or 6 pin socket on the bottom so maybe it is electronically timed but it appears to be manually cocked and fired. Unlike the Sinar shutter, the lens is not meant to be interchangeable so presumably you would have had multiple lens and shutter units. Unfortunately it doesn't appear to operating correctly (even allowing for the missing battery) as when it is cocked the shutter blades open up and stay open. Does anyone have working knowledge of this strange unit?
