Of old Colts, here are a couple of pictures of the first model Colt Officers Model revolvers. The first picture is of a first model/first type made in 1905. The second picture is of a first model/second type (changes made to the frame around the trigger guard). Colt first advertised the Officers Model in 1904 but it is very likely that the shipping started in 1905. These revolvers have a flat top frame, adjustable front and rear sights and checkered hammer, trigger and grip straps. While the finish as faded over the 100+ years since they were built, the actions are still smooth as silk. Also, these were among the first Colts to be chambered for the S&W 38 Special round instead of the 38 Long Colt. Note that the cylinders have not 6 but 12 locking notches to hold the cylinder in place. One set engages when the hammer is in the cocked position and the other set locks the cylinder when the trigger is in the forward position with the hammer down. This design changed in 1908 and was renamed the Army Special. In 1927 it became known as the Official Police model. The OM 1st Model/1st type was made for about 2 years (1905-1906) and the OM 1st Model/2nd Type was made also for about 2 years (1907-1908) making these fairly rare examples.
