PEREGRINE CLUTCH.

The clutch slip on this engine is due we think
to the working coefficient of friction being .224
whereas we have not been able to exceed .17 on other
cars.

The clutch springs Hs.{Lord Ernest Hives - Chair}667 reduce the coefficient
to this figure, and are less highly stressed. Will
you please make 3 sets as soon as possible
