Managing Director,
Rolls-Royce Ltd.,
London, England.

Attention: Mr. Hives

Dear Sir:-

Re: Radiator Tubes

COPY

We are ordering three (3) sets of extruded copper radiator tubes for test at Derby as requested by Mr. Hives.

We wish to advise Mr. Hives that we have never obtained D tubes in this material, and rather than having special dies made, we presume it will be agreeable to Mr. Hives for experimental purposes to use brass D tubes or else to use ordinary 1/4" tube flattened into a D form.

Yours truly,

ROLLS-ROYCE OF AMERICA, Inc.
