Hi, I recently acquired a nickel-plated Optimus 1S stove. This is a paraffin-fuelled 2-pint stove, which in this case is fitted with a silent burner. Originally I believe the Op 1S would have had a roarer burner as standard. I am working on the stove at present, but I have a question; Do this burner, spirit cup and igniter look as if they were made by Optimus? The spirit cup has a dimple. The curved shroud-plate shields this dimple and in operation directs the flame up to one of the small holes in the skirt of the silent burner. The shroud-plate is brazed or spot-welded to the base of the spirit-cup. Both spirit cup and shroud are made from brass, which has been nickel-plated. As I said earlier, this burner assembly came from a nickel-plated stove, which might suggest that the spirit cup has been there since the stove was made. The silent burner is marked as being made by Optimus although I have fitted later burner cups. I have never seen a dimpled sprit cup on an Optimus 2-pint stove before and always thought of them as being a feature of Svea ( Max Sievert) stoves. Similarly using a shroud-plate as an igniter tends to seen on early Svea stoves. I would be grateful for any information or suggestions. Best Regards, Kerophile.
