Not sure if it would be the same model on your 71,  but our 77 has a 
dual point Marelli as well.

What they do with it on our car, is set the second set of points with a 
different gap, and there's a vaccum switch that shifts between points 
with low or high manifold pressure.  Reason for that, is a slight 
retarding of timing and therby better smog results at(?)higher vaccumm 
conditions.  Or, maybe the other way around.

This is a "California" (says so right on the owner's manual) version 
Spider..  and of course, it was well into the smog years..

I kind of doubt your's is there for smog purpouses..  maybe performance 
ones?  I can't quite remember if I had a dual or single (or dual with 
just one set) Marelli on my 69 Berlina long ago..
