I'm puzzled by a Retina IB (Type 019II) with a bizarre shutter behaviour. I can advance and cock the shutter, and when pressing the release there is the normal "click" - but the shutter blades don't move. At first I assumed the usual jammed blades syndrome, and as the front lens element is detachable I tought I could solve this in two minutes. Hélas, not. Repeated washes with increasingly larger doses of lighter fluid have failed to produce any result, and the blades does not even show the partial movement that you can sometimes observe on heavily jammed shutters. Even trying to carefully touch the blades with a toothpick doesn't help. I'm starting to suspect that the problem may no be jammed blades. Yet the shutter mechanism itself seems ok, because it cocks and releases and when it is cocked I cannot advance. What I should possibly be looking at? |

It may still be that the blades are glued together so tightly that they didn't release. Another possibility is that inside the shutter the blade actuating link is missing the pin on the blade ring and therefore not operating the blades. You should be able to determine this if you remove the front panel and watch the mechanism operate. |

Which leads me straight to the next question: how do I remove the front panel? Even with the front lens element off, I cannot see any obvious screw or notches. |

i'm afraid i haven't done this on a retina 1b; i'd have expected the shutter panel to be removable after the front element is removed. i can't think of any other route into the shutter... |

If it is a Compur shutter, there should be a small screw near the shutter collar of which the head is partially cut away. Turn this screw (it has two holes on the head) until the cut-away section is towards the shutter center. Now turn the shutter cover together with this screw until its cams meet the (not very deep) notches on the shutter collar. |

Winfried is correct. A project for the next rainy weekend (not that there any shortage of these...) |
