It is the last model of the today important and better paid first series. From 1919, there are several changes. This includes for example a starter. This is obviously a completely different comfort to be able to sit in the car when starting, eg in rainy weather. In addition, these T models have a switching option between battery and magneto ignition. You start with the former, because that's easier. Because with the magneto ignition the engine must first create its own electricity for ignition. Thereafter is then switched on magneto ignition, which in turn spares the power supply. 08/12
