Need help to identify this Voigtländer brass lens

[maxi0909]

Hello Community, I just bought this beautiful Voigtländer brass lens, but I cannot find any exact info about it.

My Voigtländer lenses are newer in serial number.

The lens is 12cm high.
The engraving says "Voigtländer & Sohn Wien Braunschweig"
Serial Number 22280

And then there is a C engraved on the lens... That´s the problem why I cannot identify it. Never heard or read about the "C" type.

Thanks a lot

When you take the rear element group out, are they cemented together or air spaced?

The lens will arrive at my place next week... Then I could check it :)
Where´s the difference?

It's more then likely an earlier Voigtlander Rapid Rectilinear in either F6 or F8 maximum aperture later called Euryskope and each had a intended purpose like WA RR or med WA or better coverage in the slower f8 or better portraiture quality w/ the f6.

Actually, with these Voigtlander Euryscops the f6 (Series IV) version almost always has better coverage than the f8 (Series VI version.) That 'C' is a challenge. We had a similar lens asked about with an 'A' engraved in the same spot. I don't think that poster ever got back to us about it's configuration.

This is the thread you need to Read.

Or this list.

I have added this new C to our early Euryscope list.

Thanks for all of your answers, I will test the lens when it arrives, so I could tell you the exact focal length and aperture :)

My measures say that the lens must be approximately 440mm f 6.5

Which makes it look like a series IV f.6 no. 5.
