[email protected] N.B., The references below to “Hendon” is to the General Motors Assembly Plants at Hendon, London N.W.9. England. The reference to “cwt.” is for “Hundredweight”, with 112 lb. to the cwt., and 20 cwt. to the Ton. The British series S Truck was a locally assembled Utility Express [“U.E.”] Series M, itself an interim model of Series H chassis and Superior Series K motor. References to “l.h.d.”/ “L.H.D.” and/or “r.h.d.” /”R.H.D.” are in respect of “Left-hand drive” and “Right-hand drive” respectively. “C.K.D.” stands for “Completely Knocked Down” crated components. “S.K.D.” represents “Semi-Knocked Down” and “S.U.P.” “Single Unit Packs” [complete cars/trucks]. FOR THE AVOIDANCE OF CONFUSION: “T” was a “Truck” motor prefix; “R” “Right-hand drive” motor prefix, and combination of “R” with any other prefix indicated a “Right-hand drive” version of the Left -hand drive motor with that same prefix. As I do not wish to spoil the story, I refrain from commenting further on other prefixes: see below. All motors were prefixed “T” or “R”, etc. in front of the sequential engine number when I refer to “ENGINES: #” below except where stated. 1. 1924 Cylinder Blocks as used in either U.S. or Canadian motors used a Block Casting Code of # 327773 and Head Casting Code of # 327772 until the end of Superior Series F, H and Canadian “SM” prefixed motors.
