I was most interested to read your article about the Daimler 35/120 in the October issue of MOTOR SPORT and the subsequent correspondence in the December issue and perhaps I can shed a little light on the lubrication system used in the car.
The six lubrication troughs were hinged at the nearside, the other side was connected, between troughs four and five, to a series of rods which went up and out through the upper centre of the crankcase connecting to the carburetter throttle so that the amount to which the scoop on the connecting rod dipped into the trough increased as the throttle opened.
Oil was supplied via a multiple plunger pump and controlled by a mechanically operated rocking valve. The oil was drawn from the sump through a strainer into two pipes the larger of which supplied the six troughs to overflowing. The smaller pipe pumped oil up through a fine gauze filter to the main bearings, spiral gears and the chain drive of the sleeve valves.
I have pictures and diagrams if any further information is required but in the meanwhile I hope that the above is of some help.
