I've managed to buy a Linhof selected Symmar-S for £50. With a couple of problems, 1, there are a number 'dings' to the filter ring of both cells. And 2, the copal-1 shutter cannot be cocked or fired, but the mechanism does allow it to open to focus.
Does anyone know if there is a suitable tool to straighten these dings out?
It's a secondary concern but does anyone know a competent repairer in the UK? - I have an older compur shutter that the cells fit and it seems staightforward enough to transcribe the f-stop settings.
