Hi, I was wondering if you would be able to help me with some information. A few years ago I was helping clear out my grandfathers workshop and came across a spark-making gadget used for lighting welding torches. I was always told it was off a 1917 Rolls Royce, but I can find no reference at all on any parts listings. The writing on it says 'Dixie 44' followed by a list of patent numbers. I think it might be a coil/distributor. It has an advance-retard lever and a set of points on a twin lift cam. Do you know what it could be or what it is off?
