This is an exceptionally scarce example of a Kolibri Model 1 single shot pistol. Designed by Franz Pfannl of Austria, the Kolibri pistols and their cartridge, the 2.7mm Kolibri, are credited as the smallest centerfire pistol and centerfire cartridge to see production, with the pistols easily fitting in the palm and measuring less than 3 inches long. This pistol is the single shot Model 1, measuring less than 1 3/4 inches long, with the bore measuring at only approximately 2 mm, and the hammer doubling as a breech block, it is dwarfed even by its minuscule semi-automatic cousin. With this bore measurement, this pistol may have used some type of snap cap or blank rather than an actual cartridge such as the 2.7 mm Kolibri. The only markings are on the checkered grips, with "KOLIBRI" on the left and "AUSTRIA" on the right. Includes a green velvet wrapped ring-style case.
