Why so few? What is the story on the exhaust manifolds with the script? Most I have seen do not seem to have it. What years was this done/eliminated?
Ford script began to appear on manifolds perhaps in 1915 or thereabouts. Not sure when it stopped, but you are right, there are far more without than with.
And how many of those are in useable (unwarped)condition today? Anyone know when they stopped, or what was done with Canadian production manifolds regarding Ford script?
