·I just thought I'd share this interesting photo of Wilhelm Hippert.
The intent of the photo was to showcase burgeoning high-altitude oxygen technology, which is interesting in itself. But also note his pocket watch conversion. The case suggests a pre-1900's watch silver-cased watch - possible key wound. But details are lacking.
Just a photo with a thousand interesting details.
