A&M should be read as 'Aero and Motor', not 'Auto and Marine'.... d*ckhead!
If the deep head was not of Coventry Climax origin, just where did it come from? It was George himself who told be that this was an FWH, yet this is not shown on the Coventry Climax history. However, when I later tried to secure the patterns so that I could produce a proper deep head that Ian Carter had not already got at and ruined, using the designation FWH opened all the right doors. Moreover, the FW series motors were
not a fire pump engine! Clue: what does 'FP' stand for?
