Ferrari info request

[Simon Favre <simon@mondes.com>]

A friend asked about this. He doesn't own the real thing, just a
model, but is seeking perfection. The question is about the rear
end of a 1970 Ferrari 312B F1 car. There is an attachment on the
top of the transaxle right at the tail that is presumed to be a 
breather. Is there a web site that might have detailed photos of 
such a car? Is there an owner lurking out there? ;=)

The model in question is an Exoto model of a Clay Regazzoni car.
Just the thing to get a TRUE tifosi...
