I would be assuming that at the time the crankset was designed, half step gearing was still popular. So depending on intended use, available freewheel choices, and rider preferences, 50t to 48t would be the lesser range of the outside ring.
The Campagnolo records and catalogs I've seen state their smallest ring available was 46t. Sugino made 44t & 45T which if used could lower the outside ring number, but then the crankset looks odd.
