Longest horn on a rhino

[kiang]

Another inspired thread, from a zoochatter with too much time on their hands.
Looking through the Woburn pics on flickr, was the featured pic of a white rhino.
What an impressive horn (ooooerrrr missus), are there any other bigger and more impressive horns on a white rhino?
Please add pics for all other species.
Keep a rhinophile happy.

P.S Can we keep to captive animals

I'm pretty sure that this is one of Woburn's females 'Pongola' wild caught/born in African in the 1970's.

I took this pic of one of Werribee Zoo's off-display rhinos a few months ago. Alas, it isn't the best of pics, but man, that secondary (?) horn is impressive!

Doesn't beat yours Kiang in terms of length, but this guy must be getting close with his secondry horn (almost appears as if it's starting to grow into his first one!)
