ROAD SPRINGS - TESTS IN FRANCE. Referring to RL/M9.10.24. It would appear from this memo. that we should not fit any Firths springs to cars until we have proved them to be equal to Woodheads. Both cars in France will run with Woodheads springs. As soon as the Firths springs are available, we will make comparative tests on the bumping rig.
