CHASSIS B.I74.GR{George Ratcliffe} - Mr. BOURLON
(Mileage: 10.135 Kms.)

We think we have omitted to advise you that we fitted a set of L.B.B.s to the above car. They were fitted on the 14.8.35.

The particulars of the working clearance are as follows:

a - Diameter of crank pins 1 2 3 5 & 6 = 1.9985"
" " " " 4 = 1.99875"
b - Internal diameter of lead bronze bushes: 2.0015"
