D. Colt changed the name of their E frame revolver from Army Special to Official Police, branded their 22 caliber Automatic pistol as the Woodsman and branded the 2 inch barreled Police Positive Special as the Detective Special
In February 1927 Colt sent out a four page flyer announcing the branding of the Colt Automatic Pistol Caliber .22, Target Model as the Woodsman. The (A-70-8th) 1927 catalog has Official Police printed below Colt Army Special on page 6 of that catalog. Colt also included a flyer in the (A-70-9th) a later 1927 catalog that announced the name change from Army Special to Official Police as well as the introduction of the Colt Detective Special. Colt printed two versions of the April 1927 Price List (PL-11-R) with the early version still listing the Army Special and no mention of the Detective Special while the later version includes both. Also, both versions of the April 1927 Price Lists denote the Woodsman pistol where the March 1927 Price List still called it the Target Model, Hammerless , 22 Cal.
