I haven't looked at the photo yet, but '71 was the last year for the breather 
box to air cleaner hose. After that, type 3s got a different setup, which sucks 
thru a valve on the underside of the breather box directly into the intake 
manifold.

I suspect that a lot of people get mixed up by this when they use a '72-3 
engine and convert it to something different, like carbs. They no longer have a 
proper place to connect that hose so they leave it off. Unless it is connected 
to a vacuum source the crankcase will get somewhat pressurized and blowby out 
the rear crank, in front of the fan, is the result.

Now I've looked at the photo and I'm stumped, too. This is clearly an early 
breather box, and I also thought they all had the hose....
