Thorens. 1920s to 1960s
"Swiss made of the highest quality. They are almost in the class of Dunhills. Thorens was a music box maker that began in 1883. Their most sought after lighter models are of the 1920s to 1930s era. The company moved into making record turntables, speakers, and other music items. Their "Standard Original" model was introduced in 1919 and was successful enough to convince the company to continue to manufacture lighters.
"The
concept
        of the Dunhill shop was to offer the finest products.

"What
is

less
known,
however,
is
                        that between 1913 and 1964 Thorens
                also manufactured more than 5 million pocket lighters to
                help establish the

          Dear Keith,
I hope
          that my message finds you well and I just wanted to share with
          you that we have re-launched a small production of Thorens
          lighters in Switzerland. 
To
          celebrate the more than one century existence of lighters’
          production, my brothers and I are preparing a publication
          listing all lighter models including pictures, patent
          features, descriptions and historical anecdotes. 
As an
          esteemed collector, you will be of course most welcome to join
          us if you would like to share insights on an item of special
          interest that you would like to be included in the book (with
          reference to your collection).
Please
          tell me if I could provide you with any further information
          and I am looking forward to hearing from you soon.
