James D. Julia is auctioning off Ernest Hemingway's Westley Richards Droplock .577 Nitro Express double rifle. It is the gun he used on his 1953 African safari. According to Phil Bourjaily, this gun, which took a lion and a rhino, is expected to sell for between $150,000 - $200,000.
Even at $150,000, I think I better let some other gun nut have this one 
In my list of Adventurers-Whose-Guns-I-Would-Love-Own. Mr Hemingway ranks number three. Sir Samuel Baker is my #1 followed by Roosevelt.
