Hello everyone. I bought this Zeiss Ikon Ikoflex camera with the intent of fixing it. The cocking lever was not locking but I managed to fix it. The problem now is that the shutter blades remain open a little bit when I cock the shutter. Also, the trigger seems locked.Another part is blocking it from going all the way down and releasing the shutter. Could someone help me identify the exact shutter mechanism this is? I did a Google image search and it said it's a Prontor mechanism but I could not find the exact model so I can look for a service manual for it. Thank you.
