Developed in the 1920s and manufactured by A.G. Parker & Co (later known as Parker-Hale). A drift windage adjustable Patridge blade front sight and elevation adjustable "U" notch rear sight are installed. A steel housing beneath the cylinder holds the crank assembly and an adjustable trigger. It has a set of smooth hardwood grip panels. The number "2" can be seen on multiple components, including the breech assembly, trigger, and both sides of the housing.

Very fine, with 85% plus of the original blue finish, showing some scattered brown spotting, bright edge wear, and a few light scratches and handling marks overall. The grips show a few dents and scuffs, especially around the screws. Mechanically untested, but a partial turn of the crank shows clean movement and spring pressure.
