re. BUMPERS.
E1/M6.6.30.
x772
xV522.
Re. your memo. OY1/DM{D. Munro}4.6.30., the section of bumper preferred by R.{Sir Henry Royce} is half elliptical.
The tubular type is agreed to be unsuitable.
Regarding the bumper fitted to 24-EX.
R.{Sir Henry Royce} fears that this may spread the front horns if struck in the centre, and asks for a type of bumper in which this fault is non-existent.
