Experimental Test Report. This is a similar scheme to the one we have proved to be successful on the 20 HP. Road Test Report. Fitted to 4.EX Car. Test so far proves that this scheme should be as successful on the 40/50 as on the 20 HP. It cannot possibly cause any harm - we recommend it for immediate standardisation. Weight of Old Part.
