I had a metal fan blade on my '69 B break loose at speed on the 
highway.  It punctured the radiator.  That's the only time the car ever 
stranded me.

Early plastic fans could get blades breaking off, they gained a metal insert to strengthen them.  Both had more blades for better cooling, but were noisier, and cars for Swizerland had to go back to the 3-blade metal

----- Original Message -----That's an interesting piece of information! 
So now I have to find an MG dealer, who can deliver me a plastic fan.
My 1971 imported in 1990 to the Netherlands from California still has the
metal blades...
I once read a story of a broke metal fan blade protruding through the bonnet
(hood).

Cheers,

Mine has metal inserts through which the securing bolts pass.   Is that indicative of the later fans?
    And I thought my plastic fan was quieter—not by db measurement, just by ear.  
    The metal fan is hanging, decoratively, in my garage.
