Notes from Reddit re. refills:
'A quick note on vintage Aurora ballpoints: modern-day ISO G1-style refills (a la the Schneider Express 225 or Aurora’s own Wagon refill not Pilot’s G1!) are dimensionally identical to Aurora’s old ballpoint refills except the modern refills have a plastic tail. Sometimes they fit without modification, but one can also trim the tail back to get them to fit. As far as I can tell, all of Aurora’s pre-1970 ballpoints use the ISO-G1/Wagon refill, at least until they adopted Parker’s standard of refills for all of their pens. Even today, the Wagon refill is used in Aurora’s skinny ballpoints, so they are available.
So, if not Aurora’s own, Schneider 225 is your best bet.
Update: the Schneider 225 works with some minor modifications. The tip and body of the refill is slim enough to fit the pen but the plastic end of the refill is too long. Snipping it off to the right length with scissors and then smoothing the end with nail file solves the problem in less than five minutes. Thank you again for the tip!'
