Will you please order the following diabolo rubbers for the 20 HP. -
Two doz. Rubbers to F.57075 to deflect .1" under a load of 150 lbs. approx.
Two doz. Rubbers to F.57075 only over all length to be 1.250 to give .200 deflection under a load of 400 lbs. approx.
We want the rubbers as quickly as possible and in consequence are prepared to give Messrs. Dunlops a certain amount of latitude on the hardness of the rubber. Having tested them we may tell them more exactly what we require.
