I remember an independent priest, who always kept things in question. He had One ring at the genuflection, one at elevation and one at genuflection. Then he heard of one bell at genuflection and 3 bells at elevation followed by one bell at genuflection.
I don't have any problem with it, just comparing my marian missal with the 1888, Manual of Prayers, published by order of the 3rd plenary council of Baltimore. I am very happy that it was added for the purpose of the "ism" of not believing in the True Presence, if that is correct. My favorite bells are the ones with the birds!
