| NEW MODEL Houdaille (SAY "HOO-DYE") Hydraulic Shock Absorbers for Commercial Vehicles A MONTH'S FREE TRIAL Houdaille Hydraulic Shock Absorbers have, during the past 14 years, conclusively proved themselves on Touring Cars all over the world to be the only completely reliable Shock Absorbers, the efficiency of which remains unchanged over an indefinite period of years without any attention whatever. They have only one moving part which is always working in Castor Oil, wear being therefore negligible, and they should last indefinitely. To meet the large demand for a suitable and heavier type of Houdaille Hydraulic Shock Absorber for Chars-a-banc, Omnibuses, Lorries, and, in fact, all types of Commercial Vehicles and Trailers, a suitable model has been produced, and after prolonged tests over the past 12 months, they are now offered with complete confidence to all Owners and Makers of Commercial Vehicles with Solid or Pneumatic Tyres, and whether used for carrying Passengers or Merchandise. A large number are already in use with perfect satisfaction, and repeat orders are being constantly received. Wheel bouncing is entirely and permanently eliminated, and a set of Houdailles is therefore an investment. They are designed for and have been fully proved on vehicles of a carrying capacity of from 1 to 7 tons. HOUDAILLES LAST LONG AND REQUIRE NO ATTENTION. HOUDAILLE HYDRAULIC SHOCK ABSORBERS ALONE ARE CAPABLE OF 1. Maintaining their full efficiency for an indefinite period without any adjustments whatever. 2. Checking the Spring Recoil of any Vehicle to which they are fitted, progressively to the force of the recoil, and thus preventing road shocks and side sway. 3. Lasting an indefinite number of years, as there is only one moving part always working in Castor Oil. VARIABLE REGULATION AT WILL FOR ANY LOAD. Houdailles can be regulated for any load carried. It will not take a minute to change the valve regulating position of a set of four, and thus always have the recoil of the springs correctly controlled; or the position for an average load may be found, and not further touched, well knowing that the setting will never vary except at will.

HOUDAILLES GIVE THE MAXIMUM OF RUNNING ECONOMY, AND THE COST OF THEIR INSTALLATION IS SOON REPAID. The savings effected by the use of a set of Houdailles in reduced Tyre usage, prolonged life of the Mechanism, etc., due to elimination of Wheel Bouncing, in addition to the greatly increased comfort to passengers on Chars-a-banc, Omnibuses, etc., and prevention of Damage to any breakable goods, musical instruments, etc., carried on Lorries will soon repay their cost. The Commercial Model Houdaille is very easy to fit to any make of Commercial vehicle. Apply for Quotations, stating number of Vehicles in use.
