Hello everyone, I'm Patrick 52 years old, chemist, married two daughters and Titoo the chinchilla ! My family and me live in France in the big east near the Swiss border. I'm Titoo on CPL&H. I'm more specialist for the lamps, but i have some stoves that i would like to share with you. I present an old version pre 1911 Primus N°: 215, it bears the mention "patent". There is no code on the tank bottom, just number: 5. I found this stove several years ago in this state. I will restore it and revise it to try the flame. Regards, Patrick.
