I was looking up a serial number of 8D sample today.
I found this lens (not in my hands) has the interesting history supposedly.
The lens was shipped to “Philadelphia” in April 1st in 1876.

Good evening, Steven.
I have just updated the pdf.
Oh wow, a nice Waibl! BTW, do you know anything about Wcaibl?
Yes, I understand minor brands were striving for the marketing differentiations...
Good evening from Tokyo, Steven.
Thanks for your comment.
What would be the Greek numerals on the barrel, waterhouse ring inside the barrel, lens case and so on in your opinion?
Until I started...
My sample has arrived.
I identified it as
System I FL 418mm f4

Or equivalently in the older period,

I am going to receive a new flavor of Emil Busch petzvals from Finland soon.
As I don't have this brand, I started to study Emil Busch petzvals since yesterday.

When do you visit Tokyo?
What do you expect?
Edo castle (The emperor’s palace) is in the middle of downtown Tokyo near Ginza. So it’s very common and convenient to visit there....
The protarlinse was made in 1907.
Why no data before 1912 online?
I don’t know but Thiele says in the book it was the extensive research on the old Zeiss records and production books.
This book I...
Dear Peter,
Wow, I didn’t know 133mm VIIB covers 8x10.
Very nice picture!
your lens was made in August, 1904.

I think your lens is Series VII No.7.
Always refer to German catalogs for consistency to avoid misunderstanding and wrong conversions from old Austrian units to English units.
The focal length...
Good evening Steven. The lower list of VIII in Prochnow seems to be compiled from the Thiele’s book,
Which I now suspect the VIII annotations in the serial number tables are mostly typo of VII,...
This lens was made in Aug. 17th 1891, Series VIII.
Your sample is listed as 14 linien oeffnung, which is about 31mm lens opening diameter.
But your sample is engraved as VII, which could be a typo...
Wonderful collection!!!
Obsession? I bought these for studying the Cooke Portrait lens transitions.
Now I need to sell some of these for other ULF lenses though,
Keeping 15” f3.5 and 18” f4.5....
Well your sample is not listed in any catalogs above.
If there are any other Derogy catalogs in 1860’s, it may give you an answer.
It might be No.6 bis of Extra rapid based on the 1890’s catalog...
The dating by Steven is here.

So the sample would be just before 1870.
There are two No.6’s, extra rapid and rapid.

Good evening from Tokyo, Greg.
Isn’t it this series?
It’s RR and covers 100 degrees.
This series is not convertible and predates TTH VIIB as this series is listed in the 1896 catalogue.

Dear Wagner,
I updated the sample listing based on your sample analysis.
Also I made a minor correction in the transition table summary.
pdfs are available in the #6 reply.
Btw, your Orthoskop...
Dear Wagner,
Thank you for your detailed analysis and regression calculation.
Yours was made in 1878, the important year when Voigtlander changed designs, relabeled lenses and introducing new...
Happy new year everyone.
I have updated the transition summary based on the new finding in 1886 Photographische Notizen.

Good morning, Steven.
Do you have this book?
The book answers some of your questions.
I have to reread the book again carefully with google translator (sometimes incorrectly translated)....
Good evening from Tokyo, Steven.
One possible hypothesis would be copies by minor workshops or agents?
Or possibility Jamin provided signed lenses and brass works done elsewhere but couldn’t label...
You’re welcome.
A few months ago, I was looking up this Ross Zeiss patent lens owned by Craig Tuffin which happened to be the same lens as Lively’s. Check out and imagine how it would look like in...
It’s always nice to learn about the history behind a professional photographer.

Yes, that is also what I thought but not quite sure about the engraver was drunk.
Supposedly there wasn’t only one engraver but many, the one who did...
Thank you for your cooperation.
Could you give me the engraving pictures of both lenses?
Also let me know the each surface curvature, whether the surface is concave, convex, or plano and airspaced...
Bad news. Lamda Sack Company closed their business in this August.

This is a very specific question so I know I’d get very few answers but let’s try….
I have recently got the Orthoskop No.3 without aperture disks but only with the disk locking cap.

I don’t recommend doing it by yourself.
I would suggest you ship lenses to someone professional like Jason Lane….
He has an access to recooating facilities too.
I have added the Orthoskop in the flowchart and the summary table in the #6 reply.
The Voigtlander brass lens looks an Orthoskop or a landscape lens. Can you disassemble the lens to identify?
We need the front and rear lens element opening diameters.
Orthoskop info is here....
