| -6- 12. Radiator shutters. The shutters are enclosed in the radiator and the method of operation is modified which does away with the rod at the back of the radiator. Noted. 13. R.R. design luggage grid. The rear end of the frame side channels have been extended to carry the luggage grid. We think this is a desirable thing to do whatever type of luggage grid is fitted. The grid fitted to this car is enormously strong compared with the 20 h.p. or the usual coachbuilders grid. The weight of it is not excessive 14 lbs. It may, however, be possible to improve the appearance. The grid fouls the sockets and tail lamp connections. The exhaust outlet blows on the lower rail of the grid when it is fixed downwards. There is a tendency when the grid is worked up and down for the bolts which hold the grid to unscrew owing to the stiff spring washer and taper socket. The general scheme of this is approved, but the present bedstead appearance is greatly disliked. Cannot the rearmost corners be made more square to overcome this? It might necessitate a socket at corner with a radius equal to that of the tube. Are winged screws strong enough for leverage when fully weighted with luggage? 14. Gearbox and change gear mechanism. This box is fitted with torsionally free pinions and standard splines. The change gear mechanism has been made with clearance. It is suggested, however, that both the plunger springs and the spring for sideways location are unnecessarily strong. Noted. Is this the final approved position of gear levers? As the lever appears to be in the way of driver's leg except when in top gear, we wish to inspect this again on a chassis fitted with properly upholstered seat in the right position and height, and also at same time to test the strength of plunger and sideways springs. Perhaps these levers could be moved outward a little, without inconveniencing the body design. | ||
