20461-R M22-0 3-Point Prototype

20461-R M22 3-Point Prototype

Beautiful blackface 3-Point prototype mandolin, red spruce top. This is the prototype, signed February 2004, 61st instrument Hans built.

Edited description from Acoustic Music Company’s online advert: “This is a varnish early florentine 3-point style Model 22 made with Bosnian maple and topped with Adirondack spruce. The instrument is a blackface,  Schaller tuners with ivoroid knobs, 1 and 1/8″ bone nut, fine sculpted ebony pick guard, scooped extension, flat fretboard, masterful fit and finish. Custom Calton case to accommodate the elongated 3 point body. This mandolin was the prototype (and is designated as such on the label) for this model.

From Mr. Brentrup:  “The 3 point mandolin was Orville’s original (circa 1908)  florentine instrument and is a very difficult build. It has a very different sound which is well suited to old time string band music.””
