Ernest Hemingway, Maharajas, Nizams several others who don't come to mind right
Indian nobility - devoted hunters, great shots and knowledgeable folks as they were - were notorious for ordering the most expensive configuration the maker had to offer. Besides, there's room for four rifles in a howdah.
Hem had a droplock ST WR which he hated. Phillip Percival had a BLNE Lang which he loved
How about James Southerland, Major Gordon Anderson and then latter Elmer Keith and Jack O'conner. All owned droplocks with single triggers. But what does that prove?
If your asking is a droplock absolutely necessary? The answer is no.
It is however hard to deny that the droplock was innovative even to the point of genius.
Four rifles in a howdah? Gets crowded quick when there is a tiger on the head of your elephant!
