This pistol is an example of the rare and unusual Trabuzio palm pistol. These were patented in 1889 and manufactured in Italy. The magazine loads from above, and the pistol is fired using the middle finger in the loop trigger. The only markings are "01" on the left side of the barrel "16/5" on the various components, and "MADE IN ITALY" on the bottom left side of the action. It has no sights since it was meant to be used in close quarters defensive situations.
