Invented in 1890 by Catell Tribuzio of Turin, Italy, with a top-loaded internal magazine and a telescoping ring trigger assembly that collapses into itself as a safety. The pistol starts with the bolt open and when the middle-finger actuates the ring trigger it chambers a round from the fixed magazine and then fires when fully squeezed. The expended casing is extracted on release. It is manufactured without sights. "044" is marked on the left barrel flat and sideways "7" over "99" on the bottom flat, trigger, firing pin release, side plate, and inside the frame.

Very fine, retaining 85% original blue and nickel finishes with an attractive patina on the balance and a couple minor spots of pitting. Mechanically excellent.
