Well my 2113 is a couple of years older than yours - but it is exactly the same lens I have discovered this morning!
Just under 13cm in length.

I have just measured the illuminated circle to 16cm...

Yes, it is 1847/48.
This is the earliest data I have (1853).
Looks like the focal length should be about 18cm.
Something between lens 352 and 353?

I couldn’t locate that Lerebours, so here is a Hermagis which is almost identical. It is no surprise that the flat washers get lost. They must have exactly the same diameter as the narrow bottom of...

It’s posting # 63. As I posted the skeleton serial list, I’m the person has to do the up dates. I usually don’t bother to mention the individual additions to keep the thread concise. I add ebay...

There some things about this Petzval that just didn’t look right.

First of all, it was the colour of the brass. I would have sworn that the auctioneer had messed up the photos, but the brass...

I can describe what has happened with “case study 2”. The parcel was sent with absolutely no data as to contents and value (from a well know auction house!). I had even emailed that they should give...

This link is to the pirate copy of the Lens VM - the version with occasional figures/pictures. It (the LVM) is not a reliable source for non-UK...

I did a Little research when it was listed a few weeks ago on eBay Europe.
I recall that the lens mounting system looked very Projection lens like.
Searches on “Tachyskop” Lead me to data about...

I did try to convince US sellers to change their listing in the past. It is the buyer who has “hassle” with VAT due to incorrect application of rates and we can easily manage that locally.

I have...

I have been delayed by the problems of getting hold of a selection of fasteners so I can decide which system is the easiest for amateur assembly and disassembly - and a style which is not incongruous...

I refuse to bid on high value items that are linked to Pitney Global Shipping as they give no option for refunds on collectors/antique items. They are OK with low value items when “fixed...

This is just one person's experience of how import Eu/UK and UK/EU has gone.
Especialy as regards the 5% VAT rate for antiques/collectibles.

Case study 1. Export from Denmark to the Uk....

French maker of lens and French retailer with sales outlet in Berlin. Remember there is a “Krauss” in Paris as well. And Dallmeyer is hardly a typical English name, either!

LATER!

Google search...

Just off to a Grand daughter’s birthday - but yes there is a French Berthier. “Cie” is French isn’t it? More later.

I explained to custombellows that the collapsed width of the bellows is pretty unimportant, as the shortest focal length I can image is around 12”. OK, I suppose it could be used for CdeVs around 6”,...

I have too many heavy mahogany/cherry/teak/walnut cameras studio dinosaurs that came with an exciting lens mounted.
These are of the type “collection only” cameras - not so much of their weight -...

Really lens porn here

Garrett I am not guilty!
The remarks about quality of CC were made by Carlylee2002 not me - see #3.

I know better than to comment on the...

It is the lens in the second photo that is described as being originally fitted with radial drive. It is the lens lurking in the background in the final (4th) photo. The OP has managed to not show us...

Sorry, just seen this!
“Too much xylene it will set too quickly”
No - the reverse is true!
Never be afraid of thinning too much.
If you warm both glasses up to around 60 degrees C, you will find...

So, the first wide-angled Euryscopes were in fact Series VII.

My new no. 5, 28,199 without the later Series number engravings, matches the data for for the number 5 below.
Sizes up to 4 had...

A separation, cleaning and re balsaming will work perfectly, but really this so minor that I wouldn’t bother.

Here is a similar example - found on EBay!

It is patchy breakdown of the glue layer (canada balsam or early synthetics) which gives a Cloudy appearance due to separation of a solid layer on the surfaces of the two lenses. Could be due to...

This is early Voigtlander Petzval sold recently.
It has a nice engraving around the brass lens hood - not quite kosher for Voigtlander. The style of the engraving is absolutely correct and is,...

My experience is the larger the format and the greater number of cameras/lenses one owns -the smaller the annual production of negatives and time spent in the dark room.
I fortunately called a halt...

I have been patiently waiting for more contributions for many years - in vain!

Even D’Agostini’s very long list of identified Voigtlanders up to around 30,000 doesn’t produce any likely wide angle...

I found a rather attractive “wood and brass” photo of 5334 on the net. This is an unusually complete version (with 3 washer stops) and without Waterhouse slot adaption. Have added the details to post...

It is all very depressing!

In the “Good Old Days” a lot of items I bought from North America passed through the Danish Post Office with no demand for the Import VAT. Then the idea of an...

I am a bit surprised at the confusion!

Everything imported into the EU above a nominal value incurs:

1. The national VAT tax ( for Denmark, this is 25% of the total value - including transport...

I have always found friendliness and good service from “le reve edition”. I must have received the “very last!!” Jamin/Darlot between Xmas and the New Year. At least, until there are more!

I have a number of Jamin and Jamin/Darlot small size CdeV petzval lenses. The earliest of these is from around 1857 - with the very simple block letters JAMIN PARIS engraving and with no mention of...

Here is the latest take on Vienna/Braunschweig addition/final move from D’Agostini.

You might want to remove the footnote ads before the Mods discover them!

Will be adding some new info/photos during the next few hours - a lot to source but will just add on to this skeleton reply gradually. As this is most comprehensive thread on Jamin/Darlot innovations...

Well, my Christmas present arrived AFTER Christmas.
Jamin/Darlot edition. It doesn’t appear to clear up some of the confusion about the range and variations around 1855-1858 but contributes some...

Nice to see you back here Emil - we have been worried!

I hope your hardware collection has found homes which appreciate them and use them - although, unfortunately not to artistic

Yes, I have made Them from a range of sheet metals. Allow for more clearance than you calculate/Measure.
Sheaths are not necessary with book-type plate holders - in fact, they are a hinderance in...

My impression is that supply is still low, but demand is slowly going up!

Kodak 405mm. Very, very clean on Swedish Corona adapted web auction. Equivalent to 1,214 usd.

There is really very little separation with air spacing development when Canada balsam begins to break down. There are some some small areas close to the edge but by then there is an opaque sandwich...
