AFAIK HP only used the above three (MSC) controllers (for ST506), after which they designed and manufactured their own controller for their 5 (ST406), 10 (ST412)  and 15Mbyte (ST419) Winchesters.
For what it's worth, the HP controller number for their 913xB drives is 09133-69514. For 10MByte: J6 Pins jumpers (10M, One Volume and 4XX) are all installed. I've no info on The 15Mbyte configuration.

Hope that helps,
