A Bosch DR-4, 2-spark, dual magneto, fitted to the 

 right front of the engine and driven by a shaft projecting 

 back from the timing gear case, furnished spark to two 

 spark plugs in each cylinder. 



A similar shaft on the other side of the engine drives a 

 water pump and, by means of sprockets and chain, a Bijur 

 electrical generator, which is not original. 



A small tank, mounted on the front of the dash above 

 the engine, held a supply of oil. It contains a pump 

 driven by a vertical shaft geared to the rear of the intake 

 camshaft. This oil, replenished from the tank behind the 

 seats, was pumped to the bearing surfaces inside the en- 

 gine, draining into the oil pan of the crankcase. An oil- 

 level glass in the back side of the small tank is visible to 

 the driver. A shut-off valve handle projects through the 

 dash, shutting off the external oil supply to the cylinder 

 walls when closed. 



A Bijur electric starting motor, not original equipment, 

 hangs below the left rear part of the engine so that its gear 

 can engage a ring gear shrunk on the flywheel of the 

 engine. 



The frame, of 128-inch wheelbase, is supported on four 

 semielliptic springs. JM shock absorbers are mounted on 

 the rear shackles of the rear springs, while the front springs 

 are equipped with telescopic, airplane-type "jounce pre- 

 venters" made by Ernst Flentje, of Cambridge, Mass. 

 The rear axle is a solid, "dead" axle on which the rear 

 wheels turn. Truss rods at each end of the axle lead for- 

 ward to the frame of the car. Adjustments on the ends of 

 the rods allow the axle to be shifted to take up slack devel- 

 oping in the chains. Internal expanding brake shoes in the 

 rear-wheel brake drums are controlled by the hand-brake 

 lever to the right of the driver. 



The steering wheel turns a post within a column and, by 

 means of a worm and gear in the steering-gear box, con- 

 trols steering linkage connected to the two front wheels. 



The transmission, of the selective, sliding-gear type with 

 four forward speeds and one reverse, is combined with the 

 differential in a single aluminum case in the center of the 

 car, the speeds being selected by a lever adjacent to the 

 hand-brake lever. The driving sprockets of the chain
