A decent set of small precision screwdrivers. Flat head. Compur/compound/syncro compur etc all disassemble from the front ( except those on small format cameras). You basically need to unscrew the...
The larger 3.5 heliars tend to go for much more money than the 4.5 versions. All 3.5s 15cm and up are not as common as 4.5s and highly desired
Also, not to difficult to do yourself if you are “handy”. Lots of info in threads here as well as elsewhere. As long as you dont disassemble more than necessary, it is pretty simple. These shutters...
I’ve fixed a few of these. I think the iris blades are tensioned with a threaded ring on theinside of the barrel, alowing you to take apart and retension so it wont fall apart again. A useful method...
Cerium oxide, not cesium oxide!
It is readily available, used by those who polish lenses for homebuilt telescopes. I’ve used this successfully to bring life back on lenses with otherwise...
Good job! For future reference, you most likely dont need to do a full disassembly to clean or repair a shutter. I’ve repaired/cleaned hundreds and at most only had to do a partial disassembly of a...
Sorry, no parts either. I do have an intact, fully functioning B&L compound with a 3.5x5.5 B&L tessar, that looks nearly identical to yours, but is likely a size smaller.
I'll have alook as well once I'm home in a couple days. You might need a new cocking lever as well, since the levers mounted with 2 screws are much less common vs. those mounted with 3 screws, so...
Looks like a standard Petzval to me. Bigger ones, such as yours, have no focusing sleeve. Voigtlander marked their petzvals with numbers is some periods of manufacture. In your case it was after the...
There was one of these up for sale here a few months ago:

The middle element Will screw off, the giveaway Is the knurling on the edges in your top foto. There are different techniques to grip the knurled edge and if its stuck. Some may wince, but i find...
It should be easy to disassemble and reassemble if you want to clean it. If you have good materials ( cloth and solution) to do so, it's a very easy job, if not, then probably better not to do it....
The Schott glass from surplus shed mentioned above grinds well. I've made many gg screens for old German folders using that glass
Hi Steven,
There's another C lens for the list, see post 62 in this thread: #22408
Hi Steven,
From samples i've seen, the C lens has symmetrical cells, 60mm dia. Little bit shorter focal length than a bona fide euryscope IV #5, and operating at f7.
Joseph, here is the thread i referred to above:

If you look at later posts,...
It is a euryscope design, or as it has been dubbed here, a "pre-euryscope". Search on the forum for a thread on pre- euryscope lenses started by Steven Tribe and you'll learn all you need to know
Black and Decker Workmate. Folds up and you can use the bulit in clamps to secure the camera to the table. Have used this for years.
If you can remove a plate on the right side of the camera (according to your foto), and expose the gears, then you should be able to realign the gearing by loosening or removing a cog. I've found...
For these i've used small needlenose pliers, or a small, cheap adjustable lens retaining ring removal caliper, ground down to size if needed
I agree with Steven's solution of using hose clips (+ rubber strips). Screw tightening clips can be tightened reasonably precisely and give a solid grip when there's not much real estate to grab hold...
Euryskop Series II are pretty scarce, even compared to Series III, which are a lot less common than the run of the mill Series IV. Good luck in finding a correct element to fit. As Jim said, it...
Definitely get a rebate as the lack of drive will have some effect on resale value. Otherwise, i would not try to repair it, unless you get your hands on another drive that is the same size, which is...
How do you weigh a lens in a photo?
Tim
Measuring the lens glass diameter will also sort out this question quickly. A 60cm heliar has glass that is substantially larger than the 30cm.
Cheers

Portait anistigmat III f4.5??
You mean portrait Euryscope III f4.5?
Or the triplet design (licensed from cooke) portrait anastigmat f4.5?
As far as i've seen in many years looking,...
Ditto. The cells in my series III 3A have the "3A" marking on them. Note that voigtlander was beginng to make many of their components interchangable around this time (exchangable flanges, same sized...
6B was the normal designation for the petzval lens of the same glass diameter.
This should be easy to check: is your real element 1 piece or 2 separate elements? 1 cemented lens in back is the...
If your center element is permanently mounted in a housing that screws into place , then it cannot be reversed. The "reversal problem" only happens when the center element is easily removed from the...
Are you sure the focal plane shutter doesnt have a variable width opening to control shutter speed? That was pretty common on many big FPS cameras.
Some pics of the shutter setting knobs would...
It's not symmetrical. I had a 36 cm heliar where the center element was reversed. I could not get sharp focus wide open. Reversing the center element solved the problem. The difference was quite easy...
The easiest way to see what is protected, or covered, by a patent is to look at the claims, specifically the independent claims (1 and 10 in this case) the other, dependent, claims are just...
If you are looking for cameras manufactured by Voigtlander, I believe the largest were 13x18cm format, such as the 1950's Studio Camera

Great looking mods skuuterboy!
Hi Matthais,
Just try focussing with the lens wide open (f4.5) with the center lens in either orientation. It should be pretty obvious which is correct. I could not get sharp focus wide open with...
Louis called it. The barrel machined elements wont fit into a compound 4. Another opition is a zettor shutter ( this was the "factory" option for larger Voigtlander barrel lenses) or a Luc shutter....
Nice find Steven!
I noticed that another Series IIa No. 6 was sold by Westlicht a few years ago: ser# 45711. That one was missing the hood, but also had the iris with what I presume are US stops...
A barrel 30cm heliar cells wont fit directly into a compound 5. Voigtlander used different mounts for barrel and shuttered lenses, and changed this tooling often over the years. You will have to do a...
In a number of "klapp" cameras I've worked on, the winding knob did screw onto a shaft
