ADMIRALTY,
N.O. Department,
Spa Hotel,
BATH.

For the attention of Admiral Whyham.

Gentlemen,

Replying to your letter of the 21st. August, the top ball bearing is of the deep groove type and, we believe, should have adequate capacity, both to take the static load and the firing blow.

We have now provided a means of lubrication and send you a print herewith.

Yours faithfully,

for ROLLS ROYCE LTD.,
