Hello,

I bought lately from Bill a Fed 1c with slow speeds. A very interesting setting made by a skilled craftsman years ago.

Here are two photos:

Everybody can see that the lens is not in the right position. And much more interesting, there is no visible slow speed spring, like on a Leica III or a Zorki 3, for example.

When I received it, it was working, more or less. The fast speeds (except the 1/250th and the 1/500th), and one or two slow speeds (at least the second). But the ribbons and the shutters were very tired and they did not resist to my trials and they are broken now.

I have dismantled it.... To be continued!

Jacques.

PM re-sent and another through USSRphoto.
Hope you received at least one of them...

Amitiés.

Jacques I'm sorry, but I did not get anything ...

Many thanks, Alexey!
I send you a PM.

Amitiés. Jacques.

Jacques greetings!
I can help you.
Have a good mood!

After three months, my repairman cannot do the work. I let you imagine the exact answer, based on adjectives we know concerning FSU cameras: ugly, fake, home made, it looks like Leica, but... etc.

I cannot accept that. This camera represents many hours of skill and clever work to adapt Zorki 3 parts to a Fed NKVD body. So, if you knew somebody mad enough to do that at a decent price... Or even if one of us accepted... I would be delighted...

Thanks!

Jacques.

But some details are difficult to understand. What is the exact use of a slow speed spring? How could this camera work without it?

All comments are welcome. And questions too, if I can!

Amitiés. Jacques.

The second curtain is released before the first curtain completes its travel for all speeds above 1/20 th of a second, so the brake comes into use just after the release of the second curtain. At 1/20th of a second and slower, the brake is engaged a little before the second curtain releases, hence the need of that extra flat spring, and the 2nd curtain can be effectively retarded by the slow speed escapement when slow shutter speeds are used without hanging up .


I suspect that the camera's slow speed can work without that braking spring acting on the shutter roller cam but it would be hit or miss. The Leica III had that spring and so did the Zorki 3.

It's the first time too that I dismantle such a camera with slow speed.
But I was obliged to. I wanted to see inside how the mechanism worked. And I did not know that, on the three main screws which fix the shutter box to the upper plate, one was loose and another was absent. So the shutter box came wrongly and half dismounted. I reluctantly had to achieve the work before remounting all that... Three hours of researches: sorry, no photo of the mess!

I would be happy if a "knowing" forumer could tell more about the adaptation of these Zorki 3 parts on the camera, specially concerning the absence of a slow speed spring.

About the lens, it's the s/n 30439. It would go on a 1940/41 Fed S, with s/n 14xxxx/17xxxx. A correct one for this Fed s/n 73968 would be in the 22xxx range. I have several of them: once tried, they all give a good position of the infinity button (at 10 o'clock). But the presence of the slow speed button does not allow to use such a lens correctly...

Amitiés. Jacques.

I thought it is made from FED S. In this case it would have 1/1000.

I have never dismounted any camera with slow speeds. Only regular FEDs, Zorkis or Leicas I or II.
Here construction is very interesting.
Jacques M. Posted - Nov 15 2016 : 08:46:37 AM

No, 1/500th only: it's a simple NKVD with slow speeds. Not a Fed B fake!
Concerning the speeds, the first Leica III (F) had the same characteristics.

Does the camera have 1/1000 or not ?
I don't see it on 1st photo.

By what I see, the extra parts come from a Zorki 3. The slow speed dial can easily be recognized:

It is the same for the slow speed escapement box. On the left, a Zorki 3 one. One the right, this Fed's:

I don't know for the rod: I did not dare to dismantle completely my Zorki 3. But I suspect it comes from a Zorki 3 too.

Jacques M. Posted - Nov 15 2016 : 05:45:35 AM

So, I took off the slow speed dial first, thinking that probably it was not connected. But I obtained that:

The long vertical rod is pushed by the slow speed dial when turning it. On its upper part, the rod wears a piece which can be unlatched by a "tongue", just under the main speed button.

On the back, the rod wears a sort of fork, which is connected to the slow speed escapement:
