According to L. D. Satterlee, this Farrow rifle was manufactured in a wide variety of calibers covering everything that was standard around the 1890 era, including Sharps and Ballard numbers. The frame was finished either blued or nickel-plated and typical pistol grips with a finger lever similar to that used in modern repeating rifles was standard.

The hammer had a very widely curved spur, short hammer fall, and was probably one of our first "speed-action" rifles. The frame or receiver was extremely short, with the stock above the grip inletted into the metal itself, to form a secure lock. A peep sight was located on the upper receiver tang and a neatly curved cheek piece was hollowed out to fit the face. Weight ran from 8 to l0 pounds and barrel lengths were from 28 to 36 inches long.
