    Hermagis Serial numbers Need your help with a database

    Hallo all,

    Although there is some information on the HERMAGIS serial numbers with matching year of production I need your help.
    I found that mentioned list isn't very accurate so I need your input.

    If you own a Hermagis, would you be so kind and have a look if there is written any year on the front glass?

    If so, please post the serial number and year of production.
    Thanks for the help.

    Do you have Corrado's list?

    He gives exact dates for quite a lot which may mean the front glass has been looked at!
    Remember the Franco-Prussian war which would slowed down production around 1870/71.

    13657 1868
    15505 1872
    15512 1873
    16784 1876
    16944 1876

    Past auctions (Breker etc) will give some more.

    Thanks Steven.
    I haven't checked Corrado's list yet but I will do so.
    I assume your first lens is a typo...

    The 8154 is a convertible Petzval after all, the racks are screwed together. Hood is gone, no flange. Glass is 105mm in diameter, a #3 in the series with a supposedly 450mm focal length, f4.2.

    After some struggle to get the cells open, I found the front achromat only bearing the inscription "Hermagis", absolutely nothing else. (No separation whatsoever)

    The rear was assembled incorrectly but the rear negative lens bears following in pencil, although at times hard to read as the upper half of the text had a lot of damage (tight fit in the cell)

    "Hermagis - Opticien Breveté - Rue Rambuteau 18 - Paris"

    Followed in what appears to be capitals "GCC" or "OCC" (faint) and then what I thought was 1819 but the second 1 is different than the first 1 and could be a squiggly 5 ... the 9 is better to see in person after rotating and changing the light ... the image below is not the best iPhone shot either ...

    So possibly 1859 and not totally out of line with the notion that 8,000 is around 1860. We need some more lenses in the same serial number range to confirm. We by now know that the information on the lens rims changed from time to time and nothing can be assumed.

    As for focal lengths ... the front achromat is ~673mm, the rear cell is ~1,000mm and the calculated FL should be 453 with a ~190mm between cells. Measured FL is ~447mm so all is according to the catalog.

    Both front cells have a Roman VI stamped in them, most likely to keep them together.

    Cheers,

    13995 - 1867
    44064 - 1907 (? as it only writes 07 in the end of a serial number)
    8077 - ? no year written

    Thank you all.
    Just great.
    Keep them coming. This indicates that the list needs some fine tuning.....
