Hi,
I just wondered if anyone knows how best to attach the Sinar Bino-reflex housing to a Sinar F1? There is a small black metal strip with a bent spring-like metal piece screwed onto the right of the ground glass screen. When this is removed, the reflex housing fits snuggly into place but then there is nothing to hold it there and it doesn't seem to allow the strip of metal to be screwed back into place. Would be very grateful if anyone knows about this...
