Robbie, the patent dates for this box shown in the photo refer to
US patents, as each date is a Tuesday, the day on which all US patents
are issued.

The Stella section in Bowers' Encyclopedia (page 124) shows two patents
issued to Jacot, one on June 29, 1897, the other on Feb 23, 1904; both
dates are listed on the subject box.

I think the "T" in the logo is really a Swiss cross, so the "S" is most
likely for "Stella".
