    H.Duplouich lens info help.

    H.Duplouich lens, it marked on front element "GRAND ANGLE F/8 130m/m", so it's a protar design? I can not find any info of this H.Duplouich lens on internet. Thanks !

    It isn't there!

    BUT.
    It was made around 1914 (trademark and serial number).
    It looks like a carry-on from the dissymetrique anastigmat PRIOR F.8 - made from 1900-1905. I enclose the catalogue data for this one. There was a 13.6cm version with a glass diameter (front) of 20mm.

    I think it is "dissymetrique anastigmat PRIOR F.8", I check front glass diameter it's 20mm, Protar design shows in picture.
    Thanks Steven !
