The Banjo Axle now refers to the type having a nosepiece with the crown wheel and pinion which bolts into a double armed 'banjo' axle housing, but the early Austin 7 differential with torque tube bolted on to the central differential 'drum' more resembles a Banjo.
Regarding the 'loose outer ring' pinion bearing originally fitted to the 1928-1929 short nose bolt on torque tube differential (R&M or RHP MRJ 7/8 , SKF CRM 7) I have not heard of an outer ring (which should be as good tight fit in the Torque Tube nose) moving into the crown wheel.
The later fitting of a stop pin indicates that possibly this sometimes happened but with a good tight fit I think you should be OK.
The roller bearing with double inner and single outer ring lip was sometimes produced for special applications to accept very light axial thrust but this was never used in the Seven differential, given the great difficulty of aligning the thrust bearings with the roller outer flange.
