Model E draft booster cotinued

This is an original draft booster from the New Zealand bus project which I am in the process of rebuilding but also taking the opportunity to measure and scan/draw up the motor components as I have to model and recreate at least two of these. on  the back of the motor there is a 90 degree driver with a cam lobe on it to driver an AC Delco style fuel pump and on the far end a set of points witch deliver the spark in the combustion chamber immediately the motor starts up.
As I mentioned previously I use a 3d scan as a skeleton to  draw inside of my surfaces are seen as light colour and the darker colour  is where I have overlaid the scan as you can see its pretty accurate as you can see the raised part number come through on the overlay.
the last picture is the cross shaft that has the  cam lobe for the fuel pump and the breaker lobes for the points, sitting on top of another original drawing of the exact part, 20 years of collecting is paying dividends
