What ought they to be? (Sometimes it takes an enormous time for an improvement - acknowledged by HS.{Lord Ernest Hives - Chair} - to become production. R.{Sir Henry Royce} therefore thinks of cars as he knows the experimental ones, which are often far better than the production cars.)

(1) Hand brake lever next to driver.
(2) Crankshaft with larger dia. of journal.
(3) Coarse pitch back axle - 11/50 - long pinion rounded ends.
(4) Dynamo with increased number of sections.
(5) Ignition - Small cobalt Watford magneto, battery with larger condenser, Noble coil giving greater margin.
(6) Starter - RR. improved Bijur.
(7) Increased leverage to foot brake.

GOSHAWK 111.

What they will be - as above, but :-

(1) Frame joggle further back.
(2) Four speed box machined and prepared for four wheel brakes.
(3) Front axle for four wheel brakes, and radius rods, if necessary.
(4) Four wheel brakes and servo.
(5) Radiator shutters altered to double acting and vertical.
(6) Wheel carrier at rear altered for balloon tyres.
