Hi,just removed the shutter assembly from a 1955-59 Agifold rangefinder model,as the aperture blades have shifted.However,i cannot find a way into the shutter [a75mm f4.5 agilux anastigmat lens in what i believe is an AGI own make shutter]Any ideas please? |

If you look at the depth-of-field scale, in about the '4-o'clock' position you will find a small slot. This gives access to 3 grub screws in the focus ring as you turn it to place the 8, 4, Infinity positions successively by this slot. You may have to juggle the amount that you loosen these screws, so that on the one hand they clear the edges of the access slot, and on the other hand they clear the focus limit stop which is inside. To complicate matters, the focus ring is also on a thread inside the mounted housing with the depth-of-field scale.
Why on earth, I wonder, would AGI have devised such a fiddly, over-engineered design :-( ? Perhaps it's related to AGI's military contracts background. Such a system would discourage casual tampering, also it might be thought to be more dust-proof (Think sandy desert environments?) Who knows ... |

Thanks for the reply.I eventually found exactly what you have just very clearly discribed.As you say AGI had military contracts during WW11,but how we won the war I will never know if our engineering standard was as poor as what I found when I got to the aperture blades.The reason they had dislodged was because the aluminium seating for the pivoting posts on them looked as if they had been drilled out by a DIY er with an electric drill.The holes varied in depth,distance apart and were too large.I have spent many hours reseting aperture blades in the past,but these ones were a joke.Even resorting to setting them in place with vaseline did not work![you flush out with lighter fuel when held in place] Another one for the bin:-} yes happy face.......I was glad to see the back of that one. |

Ah, I just found your original post as I had got started to doing my Agifold. At least my aperture blades seem OK - phew! But, although having done Compurs, Epsilons, Prontors ... I'm not looking forward to the shutter mechanism on this one - fancy, a two-blader with 1/350 on a mechanism otherwise as complex as this! :-( |

Some while ago I had an Agifold with the same problem -dislodged aperture blades. I've still got the leather bellows. The rest of the camera went into the bin. |
