To me looks like It could be either one of what has already been mentioned or a champion tip, but don't see too many of the champs these days. Triumph and champions both have red backer pads on the tip out of the box, but backers can be added to any ferrule before gluing a tip on, so there's always a chance that It's another tip like Tommy mentioned, and was just added to a backer. it does look a little darker in color.
