The large brake drums N.sch.3571 should be used. WHEELS & HUBS. For the first two cars we are using R.W. Type Wheels, with 5.5" tyres on 18 ins. rims. STARTING HANDLE & FRONT CROSSMEMBER. These sections are shewn on N.sch. 3583. CROSS STEERING TUBE. This has been set out for the 14 ins. drums on N.sch.3578. SIDE STEERING TUBE.

The battery and box are the same as Per.2, but with a modified rear bracket for the rear as the battery crossmember is further back. See D.sch.593. FOURTH CROSSMEMBER. This is shewn on N.sch. 3587.
