S125BX distributor question

I ran across a 1973 246 GTS (euro version) with a S125BX distributor which has a 6 lobe cam, not the 3 lobe. Both points are wired in parallel and both trigger for each cylinder - they are not independent (no second condenser, no opening in the distributor body for the second terminal contact). There is no carburetor microswitch and no indication that the engine ever had any emission controls installed. I have not found any documentation regarding this configuration as all 6 lobe cam S125's seem to be the C models.

Does anyone have any knowledge of this configuration in a BX? If it's not a factory configuration, any thoughts on why someone might have replaced the 3 lobe cam with a 6 lobe? And yes, I did ask the current owner, but he was not aware that the BX should have a 3 lobe cam and assumed the current configuration was standard.

JD- For US Dinos and Daytonas, that was a standard set-up with one pair of the points retarded at low revs to improve emissions. My 02984 had the same twin points on a 6 lobe distributor.

Every day I look around, and if nobody is shooting at me, it is a pretty good day.
