I am handing you herewith blueprints F.70305 and F.70323, giving full details of the front and rear springs. It is, of course, very important that we should not give Messrs. Firths any information that can be avoided as to why the springs are required and therefore I think it would be advisable to state definitely that we are making some experiments with semi-elliptic rear springs, to confirm, or otherwise, our previous use of same. In regard to the particular poundages to order the position is as follows:- Front spring F.70329. poundage 1000. number off 2. " " F.70330. " 1050. " " 2. " " F.70331. " 1100. " " 4. " " F.70332.
