Here are both the horns on the skull are just under 19 inches on the in side.
The mass on the single horn is just incredible. I am guessing the deer that the skull came from died in August,because the end of the horns were eaten away like they might have been in velvet,also because of the very rough texture of the horns them selves.They have very sharp little knobs that don't appear to have been rubbed.
But really who knows.
