Mr. J.R. Quain,
Electrical Engineer,
17, Victoria Street,
Westminster.

Dear Sir,

We have received your letter of the 1st inst. with regard to radiator water heater and cigar lighter.

With regard to the radiator water heater, you do not say for what wattage this is arranged. We are of the opinion that the drain on the car battery which would result due to an effective apparatus of this kind, would be a good deal more than could be reasonably expected from the dynamo battery system as arranged only for lighting and starting.

With regard to the cigar lighter, this we are putting before our Sales Dept. as the matter of such an accessory does not concern us here at Derby.

Yours faithfully,
