RE. 12-G4. COUPE. X.5830 X.4538

We understand from you to have said that the Barker Coupe Limousine (semi-flexible) weighs 32 cwts. for the complete car. Assuming a std. chassis weight and spares this gives a coachwork weight of 9 cwts.

We are aware that Weymann bodies are not necessarily light, but we are surprised at this figure, for the Hooper 6-seater Sedanca, panelled, and with division, only reaches 9 cwts.

We think that you should weigh the India(Production 20 HP. with 4-speed box and Front Wheel Brakes) chassis as soon as possible, so that we can see how much weight has been added by :-

(1) The cross in the frame.
(2) " 3" of extra wheelbase.
(3) " new back end of the car.
(4) " new engine feet.
(5) " raised radiator.
(6) " cast dash.

We think you should then weigh the complete car carefully noting what accessories and spares are on board at the time, also the oil and water.

Such a body as this, built on the lines of the sports car, could be produced at 5 cwts. at the most. We proposed doing this with the 3rd. body, the close coupled Coupe cabriolet.
