Hs{Lord Ernest Hives - Chair}/Les.11/JH.23.9.36.

After five attempts, The Harboro Rubber Co.Ltd., have been unable to obtain satisfactory rubber-to-metal adhesion for Part No. FW.180. The difficulty has arisen owing to the soft grade of rubber required.

As the British Tyre & Rubber Co.Ltd. are producing satisfactorily very similar rubbers for Phantom III will you please transfer this item FW.180 to them. The mould used by the Harboro Rubber Co.Ltd., has been returned to us and can be sent to the British Tyre & Rubber Co.Ltd.

We attach copies of our recent correspondence.

Hs{Lord Ernest Hives - Chair}/Les.{Ivan A. Leslie}

Att: copy of letter from Harboro Co. dated 22.9.36. and copy of Hs{Lord Ernest Hives - Chair}/Les.16/KW.23.9.36.
