He joined Col E M Campbell Clarke, a Royal Artillery officer, the deputy superintendent of design who, in 1938 was promoted to vice-president of the Ordnance Board. MacLeod Ross was a devoted disciple of Clarke, as he makes clear in his book. Clarke was credited with the design of the 25-pounder gun and the range of British anti-tank guns. No mean achievement, even for a gunner although his record on tanks such as A7E1 to A7E3, the Light Tank L4E1 and the Morris armoured car did not redound to his credit. This is an excellent book for someone who is looking for a different perspective on tank design and the intricacies of manufacture and logistics. ; 8vo 8" - 9" tall.
