Troeh used a Smith; Arie a Marlin repeater.
Arie used a Parker SBT as an industry rep in 1921 but returned to the amateur ranks after one year. At the 1921 Grand, he tied for the professional championship.

He used a Model 12 for most of his career. Here with Bart Lewis who was Amateur Championship of the US with 195x 200 at 22 yards at the 1913 GAH. He used a Crown grade Smith to win the Grand American Doubles in 1926
