A 1903 pistol colt, made in Colt Company which was presented by Jabelonsky to Mohammad Reza Pahlavi (the last king of Pahlavi dynasty) is on exhibit in Royal Weapons Museum.
This colt which is in the first floor of this museum was designed by John Browning and built by Colt Patent Firearms Manufacturing Company of Hartford, Connecticut.
The Colt Model 1903 Pocket Hammerless is 32 ACP caliber, self-loading, semi-automatic pistol. The Colt Model 1908 Pocket Hammerless is a variant introduced five years later in .380 ACP calibers. Despite the title 'Hammerless', the Model 1903 does have a hammer. It is covered and hidden from view under the rear of the slide. This allowed the weapon to be carried in and withdrawn from a pocket quickly and smoothly without snagging.
Royal Weapons Museum is located in the north of Saadabad complex. Originally this building was the residence of Mohammad Reza`s brother, Gholam Reza Pahlavi. This collection contains more than 70 pieces of war weapons and numerous hunting rifles made in some of the famous manufacturers such as: Remington, Winchester, Spring Field and Brno and etc.
