The maharaja
I have a few pictures of the man, none of the exact age he was during the Delhi Durbar in 1903
Young in this one, but the jacket is quite similar to the one he wore during the parade.
He was 39 at the time of the Durbar so not sure if this might be a bit old for it or not.
If you check in the photos I used to make the elephant you'll see that the beard can hardly be seen, although you can see same shades of it and the moustache in some pictures. So I'm assuming that his beard was gray.
These are the escort guards and the masters
