I believe this caliber was introduced in 1906, so this would certainly be one of H&H's early 500/465
Royals. Many of the early ones were Dominion Grade Sidelocks. This specific rifle was made
for the Marquis de Peneranda & was part of a 2 gun set. I am trying to get some more info
from H&H. I would love to find out what the #1 rifle was?

Nigel, by the way, my first elephant was taken with the 450/400 Charles Lancaster double
you sold me about 7-8 yrs ago. Had this H&H not come available, I would have been perfectly
happy continuing my hunting career with that rifle. (see pic below)
