[Avodah] Kohain question

[Rich, Joel]

The medrash darshens the pasuk - "Vhakohain hagadol me'echav asher yutzak al rosho shemen hamishcha umilei et yado llbosh et habigadim et rosho lo yifra..."  as follows-:
Vhakohain hagadol me'echav  - zeh kohain gadol
asher yutzak al rosho shemen hamishcha - zeh mashuach milchama
umilei et yado llbosh et habigadim - zeh mrubah bgadim



Questions:
1. Before the shemen hamishcha was hidden, was there ever a kohain gadol who was "installed" by being mrubeh bgadim?  If not, was this method transmitted as a fail safe bdieved?

2.AIUI there is no other hint that there was a mashuach milchama  (i.e. that required anointing) - given the "holiness" of the shemen hamishcha, any guess why this additional recipient isn't mentioned outright (the only mention is a drasha that a plain kohain can't do the speech by a comparison to the shotrim who must be appointed

3.once the shemen was hidden, was there a mashuach milchama?
