This is Coran Horn and Whistler his Astromech droid from the Novel        "STAR WARS  I JEDI".
I repainted an R2D2 green to make Whistler.  I used a Dagabah Luke for Coran Horn.  I sanded down the hair and painted it white and added the goatee.
This is what he looked like when he was undercover looking for his wife.
