The gun was made by T R Hasdell in Chicago. L C Smith had a little Pee Pee contest with over who's guns were choked better. I believe TR Hasdell only made or finished guns in the USA for about 4 years. Here is a link to the LC Smith article where TR Hasdell was challenged

The gun is bored with about 3 1/4" chambers and long tapered chokes, and does pattern very well. A friend and I shot about 20 hand thrown pigeons and the gun performed remarkably well on these birds.
