Hermo was a trademark owned by the French camera maker Hermagis.
I have never seen this lens but I would say it is from the 1930s. At that time, Hermagis sold a rebadged copy of the German 3x4 folder Zeh Goldi under the name Cady. But lenses for folding cameras came in shutters while this lens obviously does not.
The lens could come from a box camera, as box cameras usually have rudimentary shutters behind the lens and Hermagis had a few 3x4cm box cameras with 50mm lenses that used 127 film. But f/3.5 was quite fast then and such a lens would not have been used on a box model, which was a cheap entry-level camera generally equipped with a fixed focus f/11 lens.
So, in my opinion, this lens must probably originate from a stereo camera. Hermagis had a few models and these cameras have twin coupled shutters built inside the body, rather than the usual lens in shutter. On the picture, the lens focusing cam looks quite worn-out. Stereo cameras were often equipped with a coupling rod linking the focusing tabs on both lenses and that could explain why the base of the tab has lost its chrome.
Here's a picture of an older stereo camera showing the coupling rod between the lenses :
Cheers!
