{40K} Dark angels Baneblade

Hi All,

The guys at my local store have put together a decent Baneblade
painted up with dark angel colours and iconography. Looks really
good. I am sure I remember seeing something similar in one of the
recent White Dwarfs or one of the Apocolypse books in a picture or a
painting. Does anyone know if there is a back story to this as I
thought the baneblades were attached to the IG rather than the SM?

Regards,

Fin
