Hi all, I present the action of my Optimus N°:200, it is great form. I bought it a few years ago, but it was impossible to use with kerosene because there was the adapter for alcohol on the mixer tube. This piece was very difficult to remove. In my new home i set up the workshop to do the job comfortably. Yesterday i managed to remove this piece, the rest was ready for severl years. After technical review i monted an Optimus mantle filled with fresh kerosene and here is the light for everyone ! I will present this lamp in the gallery reference. Thank for watching. Regards, Titoo.
