Hi all Here is my last restauration project : A model 112 swan neck lamp from Guenet et Abbat (or Louis Compain ?). Production year ? After 1921 because this burner was patented in 1921. This burner is in a 1926 G&A catalogue, after, I don't know ?? I am not sure who is the owner of the "Succès" brand . I guess this was G&A because all patents are from Guenet et Abbat from 1909 to around 1947. second hint : I have never found a patent claimed by Compain (who was also a seller of bicycles and motorcycles in Paris in the 30's) Third hint : The "Comptoir Culmen" was the "syndicat des commissionnaires négociants en gros du cycle, de l'aviation, de l'automobile, des sports, 10 rue de Lancry, Paris) this can be translated by " commissioners wholesalers trade union " My guess is that louis Compain was only a retailer, until the proof of contrary ;-) For this hour, I am fighting with the 101 burner. All spares seems to be present although the needle is a little poor in quality and the needle system completely jammed. here is the dismantled burner ; funny puzzle, don't you think ?
