This A/ has a melody (IIIa) in PsM1981, another in AM2000s (T3 p. 430, IIIa too), both of which do not match H at all. Zw and Ka match PsM81 loosely but are VIII. H is in the same family but significantly different. I chose the most recent restitution (AM2000s T3) with no clear view of how it was established.
