Here is an aurelianus from the fourth emission from Lyon (3,3g - 20-23mm). It is not in Bastien with this obverse legend IMP C C VAL DIOCLETIANVS P AVG. Should come after #137.
I don't know if it is in supplément 1 or 2 but it confirms the #137 note which indicates that Voetter had mentioned such a legend for this bust in the fourth emission with no workshop number.
