    Emil, this is surely a continuation of the de Pulligny and Puyo design with just 2 symmetrical meniscus lenses at each end (which you are probably hoping for too!).
    Their's (P&P) is described as a non-chromatic lens too.
    Duplouich is a very French domestic brand with a reasonably large production. Even I have one - a mere projection lens, though!

    Indeed - I hope...

    This is the text that followed the add:

    "The H. DUPLOUICH Anachromatic lens is an "Artist’s lens". According to Duplouich, "The principal characteristic of these lenses is that they give a soft image commonly called ’chromatic blur’ at all apertures. Covers 13x18cm."

    If we're right I think I got a good deal... And I am anxious to see what it can do..

    Well, this is a very well informed (I think) seller who probably has access to some printed material (French?) that we don't have (yet).

    Should be an interesting lens! And a good alternative to that Berthiot Hyperchromatic you were denied.

    "The principal characteristic of these lenses is that they give a soft image commonly called ’chromatic blur’ at all apertures..." refers to the chomatic aberrations being only weakly dependant on aperture size, unlike spherical aberration, which is strongly dependant on aperture size.

    I wonder what the construction is... Most achromats are corrected by having two different types of glass, in the old ones, crown and flint, with different refractive indices.

    Emil, you must ask the seller where he got his information from about Duplouich.

    I found not more than that :
    H. Duplouich was a collaborator to Edouard Lutz and followed him in 1896 as the owner of an optical firm founded by Berthaud in 1848. Duplouich specialized in photographic lenses and operated his business in Paris, 5 rue du Pont de Lodi. He also sold wooden cameras (probably designed if not built by the firm).

    Merci, Dominique!

    So he was active around 1905, when Darlot gave up the ghost and the double meniscus P & P design was left in the air.
    A new boy would be more likely to adopt the modern black finish.
