1915
Elliott's last competition was in 1911
Sporting Life Jan 13, 1912
Another veteran of the shooting game has passed out of the professional ranks. He is James A.R. Elliott, of the Winchester Repeating Arms Company, one of the greatest trap shooters who ever lived. Elliott was connected with that company for 19 years, and had a wonderful following in the shooting world, particularly in New York State, which has been his territory in recent years. In advising his friends of the severance of his connection with the Winchester Company the veteran says that in his long service his relations with the members of the company were ideal.
He continued to travel promoting his “Elliott Ear Drum Protector” thereafter
