Actually no. If you have this setup:

A) Vet with 70
B) RAF
C) RAF

None will get RAF Kill Bonus nor Quest Turn in bonus.

If you had
A) Vet (Lowbie)
B) RAF (Lowbie)
C) RAF (with transferred 70) such as I have then:

A) gets no Bonus (except XP bonus when you drop the 70 out of party), B) Gets XP bonus and Quest Bonus .
