I am sure it is Hartzell, but the equipment list says only “Dwg 7-1509.”

Anybody know for sure the part number on our Decathlon prop governors, and manufacturer? I could look, but it is almost like pulling the engine to get to it.

No - but I suspect that McCauley could be used on any Lycoming. The prop is Hartzell, but I don't know for sure that the governor is.
I am not the only one who will have this question - all constant speed Decathlons will need the following log entry:

AD 2020-19-06 - N/A by governor manufacturer.

I want to say I saw in my aircraft manual that the governor was Woodward. I'll dig it up.

My Service Manual for 8KCAB '72-'79 says the following:

150HP - Hartzell F6-3A or F6-31, or Woodward D210688
180HP - Woodward D210688
