| Mr Darrington for E.C. X496 3300 May 20th.1918 RE VENTILATION SCHEME. Further to my previous reports on this matter, please note that the louvred side guards should show to advantage on "A" Steering cars, as there is not so much room under the floorboards "when standard" as on the L to M type cars.
