Over the last then years I collected frame numbers and pictures of old Swiss bicycles as I always wanted to know their age. Beside in the internet I found lots of old bicycles at Swiss railway stations and in Swiss collections and museums. Meanwhile I have a huge database with old Allegro, Mondia, Condor, Cilo, Tigra and many other brands. Valuable information I also got from old Swiss bicycle newspaper which date back as far as 1889. ...
Thank you, Michael, for the work you've put into this!
May I have your opinion on the serial number 165167? I assume 1959 or so.
