Hello
I have just bought a cosmetically and optically excellent post-war Ikoflex with a non-working Pronto 11 shutter, drenched in (?)WD40. I suspect it is likely to unsalvageable. Anyone have a working one, know where I can source one or know if any other type of shutter will fit?
Thanks |

First thing you have to do is get that shutter out of there, and clean it with some lighter fluid. WD-40 has a lot of water in it, and will corrode things before you know it. You'll most likely have to clean out the whole camera, as WD-40 will also creep everywhere. Which model Ikoflex are we talking about here?

Ikoflex 1 (850/16) with prontor 11 shutter and Tessar lens. Dates from early 1950s |

Let's hope it is not WD40 but another oil. I have cleaned out several Prontor shutters which did experience an oil-bath during their lifetime and all could be put to work again. It involves however a complete stripdown of the shutter. |

Sorry
Correction to my 2nd post - the shutter is is a 'Pronto 11' not a 'Prontor 11' |

An Ikoflex with a Pronto II seems rather rare to me. But then again those years were very difficult for the German camera industry so, who knows, maybe they had such a model.
If it's really a Pronto II (or even a Prontor II) chances are that these were indeed made by Gauthier themselves and you have more chance sourcing parts from another camera type.
What are the shutter speeds ?
Why do you think that it is not salvageable ? Can you see any mechanical damage ? |

Thanks to everyone for their help so far with this.
I have obtained a copy (courtesy Mike Butkus) of the original Zeiss manual, which clearly states 'Pronto' 11 in this configuration. I do note though that the 'Prontor 11' seems, from what I can tell from looking at this shutter on other cameras, to have a very similar specification and levers positioning - which is why I asked in my original post about possible substitutes. I have taken the shutter cover off but there is no lettering to indicate which model it actually is.
I will try to get the shutter out of the carcass as soon as I can and post again on information. I described it as unsalvageable, meaning unsalvageable by me, other than a lighter fuel soak.
Thanks again everyone
Best wishes

CORRECTION
It is the 'Prontor-S' which appears very similar. |

Yes, the Prontor-S is indeed a shutter which surely is used on the Ikoflex.
I have made a Flickr set of images about its successor, the Prontor-SV which you can find here : Ikoflex 1a Prontor-SV
As said before a tear-down and cleaning is the best. If you only want to wash in lighterfluid then you have to remove the optics first !!
Lighterfluid dissolves old lubricants but leaves deposits behind on the places were it runs to and evaporates. You don't want your lensglasses being spoiled by that. |
