| -2- should hardly say they are perfectly rigid. Again, the 20 HP. wheel is higher in relation to the frame than the S.S. wheel, which makes the tubes correspondingly longer. We have proved on the pump that the S.S. carrier plate suffers from precisely the same complaint as the 20 HP., and send you under separate cover, some bolts from the carrier showing how the plate has been moving about. In case you should be thinking of 14-EX carriers as models of the S.S., we remind you that these were fitted with the old type of screw bolt, which gets a better grip of the back plate and prevents the initial wheel movement which appears to move the plate about.
