We have already fixed up our chief dimensions of:- (a) HP. 11.9-12.HP - 1500 CC. 6.cyc. 2.2 bore, and 4.5 stroke. (b) Track 52". (c) Room for body behind dash 99". (d) Size of wheels 760 X 90 to 100.

I do not like the scheme of wire wheels shewn in the D.F.P. Catalogue for this chassis, and would prefer disc. Also the body must have a proper windscreen and hood which when up is attached to the windscreen, and weath- Handwritten notes: * See memos at end 10-3-22 Ev {Ivan Evernden - coachwork} to Hs {Lord Ernest Hives - Chair} , Br, DA {Bernard Day - Chassis Design} 17-3-22 R to C, BY, Hs {Lord Ernest Hives - Chair} & EP {G.
