Designed by Friedrich Pfannl of Austria, the Kolibri and its cartridge, the 2.7mm Kolibri, are credited as the smallest centerfire pistol and centerfire cartridge to see production, with the pistol easily fitting in the palm and measuring less than 3 inches long. Manufactured with a notched groove sight on top of the slide, with "FP" imprints on both grips and "KOLIBRI" on the right grip panel. The case is finished in an emerald green leatherette material with impressed ribbon and geometric decoration with a green silk and felt inner lining, the former marked in gold "Mon MARQUIS/L. TETARD Sr/4 Bd DES ITALIENS/PARIS". Monsieur Marquis has not been positively identified, but the Boulevard des Italiens was a center of upper class Parisian culture in the late 1800s and early 1900s, which would be a prime target market for such a dainty and novel pistol. Also included with the pistol is a small metal cartridge box and approximately 25 rounds of ammunition.
