re 58-GN
Sg{Arthur F. Sidgreaves - MD}15/E9.9.32

Thanks for Hs.{Lord Ernest Hives - Chair}10/AD.8.9.32. I have not yet driven this sufficiently to express any opinion.

Cx.{Major Len W. Cox - Advertising Manager} and I went down to Brooklands yesterday evening to make some comparative tests with 85-JS{Mr Johnson's Secretary} because Cx.{Major Len W. Cox - Advertising Manager} was anxious to know whether 58-GN was good enough for the American who criticised 85-JS.{Mr Johnson's Secretary}

We made some comparative side by side acceleration tests from 10 m.p.h., 20 m.p.h. and 30 m.p.h. on top, and in each case found that 58-GN was slightly better than the Continental but not sufficient to warrant our asking the customer to try it.

58-GN has of course a very much heavier body, but to compensate for this a bit there were two people in the Continental and one in 58-GN.

The weather conditions, wind and rain, were too bad for me to take the opportunity of making any test of a maximum speed or lap speed but I will arrange to do this as soon as possible.

In regard to the steering I find the friction is too great because as set it has robbed the steering of its castor action on cornering. I have asked Crawford to slack it off slightly on this account.
