Dear Sirs,

With reference to your letter of the 28th ulto; regarding H.T. Cable suitable for a Marine Engine, we have looked into this matter and we suggest that you use the same Cable as that in your Chassis Dept; i.e. Uniplug Cotton No.2. to Air Ministry Specfn. D.T.D.2002.Section D, but with Neoprene and 19/.012" tinned copper wire.

The approximate overall diameter of this material would be 7 m/m and if you will advise us whether this material will meet your requirements we shall be pleased to go into the matter again with a view to submitting our quotation for the quantity you are at present requiring.

Yours faithfully,
BRITISH INSULATED CABLES LIMITED.
