    Nope, I missed it !

    I have 2 or 3 Maugey lens cells with achromats (81 and 95mm diameter) and I don't believe they had Hermagis on them but I'll have to look again.

    Good find !

    Cheers,

    This completed listing has surely been seen by most correspondents in this thread

    Anyone know who ended up winning the lot of Hermagis glass? I have a No.3 Petzval that is missing an element in the rear group.

    I have once had success in contacting an ebay winner through contact with the seller. I don't think this is against ebay rules.
    But you have to convince the seller that your approach - with a wish to have a mail forwarded on to the winner by the seller - is completely ethical.
    You could always use this thread as a reference and a wish "to add to the knowledge of the house of Hermagis"!

    Oh, I should add the serial number. No. 3 'Normal' Petzval 13,981. Though the edge of the front achromat is marked 1888. Perhaps that second 8 should be a 6. Mis-marked possibly.

    Interesting example of a pre-serial number Hermagis stereo pair with both cup aperture inserts present.

    I have two "Trousse(s) Aplanastigmatique(s)" from around 1930:

    N°7 for 13x18: n°118486

    N°5 for 18x24: n°275717

    (Extra rapide) Objectif Portrait Serie II No.1 390mm f3.5 No. 272583
    No writing on the sides of all elements except X by pencil on the front doublet.
    Black enamel finish on brass with no SOM Berthiot engraving, so it was made circa 1934 I suppose.

    Just to present a nice example of an early Objectifs a transformations (convertible) or rather the lens edge writing on the front achromat.
    This is before date/year writing was started, but after 1857 when serial numbers were introduced.
    This is the smallest Petzval/Landscape lens made by Hermagis:

    Size no. 6
    Lens diameter 44mm
    Focal length 12cm made for Medaillons (smaller than CdeVs) - Landscape achromat up to 11x15cm format

    These convertibles are very complex with their many brass sections. This one has a later conversion to WHS, but the original structure is unchanged. The barrel unscrews into 2 halves, with both halves having a section of the focusing track. There is a cute solution to make sure that the two tracks will always be aligned when screwed in - no matter how much the threads wear. There is a tiny raised steel tap 0.5mm on one half, whilst the other half has a channel, which the tap can enter. It stops up against a barrier which coincides with the tracks being opposite each other. Strangely enough, this tiny convertible only has a track on a single half of the barrel - so the ingenious system is completely superfluous for this lens.

    Added to the database.
